IRF840 MOSFET Datasheet, Pinout, Features, Equivalent & Applications

Hi Fellas! I hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to IRF840.

The IRF840 is an n-channel power MOSFET. It is a fast switching and high voltage device that is available with low on-state resistance. As this is an n-channel MOSFET here conduction process is exercised by the movements of the electrons. In other words, though conduction is carried out by both the movement of holes and electrons, electrons are major carriers in this case.

I suggest you read this entire post till the end as I’ll discuss the complete Introduction to IRF840 covering datasheet, pinout, features, equivalent, and applications. Let’s jump right in.

Introduction to IRF840

• The IRF840 is an n-channel power MOSFET that supports loads up to 8A and 500V. It is a fast-switching and high-voltage device that requires 10V across the gate terminal to initiate the conduction process.
• This IRF840 MOSFET is a three-terminal device made of gate (G) drain (D) and source (S) terminals. The external circuits are connected with these MOSFETs through these terminals.

• This is an N-channel MOSFET, here the conduction process is exercised by the flow of electrons in contrast to the P-channel MOSFET where the conduction process is carried out by the flow of holes.
• It is important to note that conduction is a process that is carried out inside MOSFET by the movements of both electrons and holes but electrons are major carriers in the n-channel MOSFET devices while holes are major carriers in the p-channel MOSFET devices.

• The MOSFET stands for Metal Oxide Silicon Field Effect Transistor. It is also known as the IGFET Insulated Gate Field Effect Transistor. It is made by the controlled oxidation of a silicon semiconductor material.
• MOSFETs and BJTs (bipolar junction transistors) are considered as different semiconductors as BJT is a current-controlled device while the MOSFET is a voltage-controlled device.
• The voltage applied at the gate terminal usually is directly related to the current between the source and drain terminals. The gate terminal voltage controls the current at the drain and source terminals. Simply put, the gate terminal acts like a control valve that controls the current between two terminals.

1. Source (S)
2. Gate (G)
3. Drain (D)

1N5818 Schottky Diode Datasheet, Pinout, Features & Applications

Hi Guys! I hope you’re doing well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to 1n5818.

The 1n5818 is a Schottky diode. It is also known as a hot-carrier diode that is employed for extremely fast switching applications. It carries high forward surge capability and low forward drop voltage, making it a suitable pick for high-frequency applications. It is available in the DO-201AD package and comes with very small conduction losses.

I recommend you buckle up as I’ll discuss the complete introduction to 1n5818 covering the datasheet, pinout, features, and applications. Without further ado, let’s get started.

Introduction to 1N5818

• The 1n5818 is a Schottky diode that is incorporated in extremely fast switching applications. It is also known as a hot-carrier diode.
• It is available in the DO-201AD package and comes with low forward drop voltage and high forward surge capability.

• MOSFETs semiconductors are the appropriate alternatives to these Schottky diodes and where less power dissipation is needed, MOSFETs replace these Schottky diodes.
• Low electronic energy in an unbiased condition is responsible for the formation of a barrier on these Schottky diodes that restricts the movement of electrons. This barrier formation is the main reason these diodes devise are also named hot-carrier diodes.
• Know that… generally, both the Schottky diode and regular diode are the same devices in terms of the current flow i.e. both devices support the conduction process in one direction only and restrict it in the opposite direction. And current flows from the anode pin to the cathode pin.
• These devices, however, stand different in terms of the voltage required to power up these devices. Both components receive 2V DC source voltage out of which the Schottky diode requires only 0.3V leaving behind 1.7V to power up the diode devices. And regular diode requires only 0.7V, leaving behind only a 1.3 potential difference to power up the component.

1N5818 Datasheet

Before applying this component to your circuits, it’s wise to read the datasheet that details the main characteristics of the device. Click the link below and download the datasheet of 1n5818.

1N5818 Pinout

• The following figure shows the pinout diagram of the 1n5818 device.

• This power diode carries two terminals called an anode and a cathode. The external circuits are connected with the diodes through these terminals.
• And current flows from the anode terminal to the cathode terminal.
• The anode terminal is positive while the cathode terminal is negative.
• The current enters the diodes from the anode pin while it leaves the diode from the cathode pin. Again, the current flows in one direction only.
• You cannot force this device to flow current in the opposite direction. Doing so will damage the device and thus the entire project.

1n5818 Schottky Diode Construction

• The 1n5818 is made by the mixture of metal with the semiconductor material which results in the creation of a barrier.
• When metals like platinum, tungsten, chromium, and molybdenum are joined with the n-type semiconductor material, they create a Schottky diode. The n-type semiconductor is the semiconductor material where electrons work as major carriers and holes work as minority carriers.
• The Schottky diode comes with two terminals called anode and cathode. The anode side is positive and the cathode pin is negative. The anode pin is made of metal material and the cathode pin is made of semiconductor material. Know that... the current enters the diode from the anode side and it exits the diode from the cathode pin. The current moves from the positive anode side made of metal to the negative cathode side made of semiconductor material.
• The forward drop voltage of the Schottky diode is mainly dependent on the nature of the metal and semiconductor material that is used to create the barrier that blocks the movement of electrons.
• Both n-type and p-type semiconductor materials can be employed to operate as a cathode terminal in Schottky diode, but n-type materials are preferred over p-type material because the latter carries with low drop voltage.

1N5818 Features

• Guarding for overvoltage protection
• Very small conduction losses
• Carries high surge capability.
• Contains low forward drop voltage.
• Extremely fast switching
• Available in package DO-201AD.
• Low forward voltage drop

The IRF830 is an n-channel power MOSFET where conduction is carried out by both electrons and holes but electrons are the major carriers and holes are the minority carriers. It is a high voltage and fast switching device that comes with low on-state resistance. You can also check this post on the Introduction to IRF730 that I’ve uploaded previously.

I suggest you buckle up and read this post all the way through as I’ll detail the complete Introduction to IRF830 covering datasheet, pinout, features, equivalent, and applications. Let’s get started:

Introduction to IRF830

• The IRF830 is an n-channel power MOSFET where electrons are the major carriers and holes are the minority carriers.
• It is widely used in amplification and switching applications of electrical circuits.
• The MOSFET stands for Metal Oxide Silicon Field Effect Transistor which is produced by the controlled oxidation of a silicon semiconductor material. It is also known as the IGFET Insulated Gate Field Effect Transistor.

• This device is an n-channel MOSFET which means the conduction is carried out due to the movement of electrons in opposed to the p-channel MOSFET where the conduction process is carried out by the movement of holes.
• Know that, the conduction process is done by both the movement of electrons and holes but in the case of n-channel MOSFET the major carriers are electrons and in the case of p-channel MOSFET major carriers are holes.

• With a maximum drain-to-source voltage of around 500V, this IRF830 MOSFET is a three-pin component made of gate (G) drain (D), and source (S) terminals. These terminals are used for the external connection with the electrical circuits.
• In terms of the controlled value, the MOSFET is different from the BJT semiconductors. The MOSFETs are voltage-controlled devices while the BJT (bipolar junction transistors) are current-controlled devices.
• These devices, however, are the same in terms of performance and efficiency. Both are high-speed and low-power loss devices.
• The voltage at the gate pin controls the current between the source and drain terminals. The gate terminal behaves like a control valve that controls the conduction between source and drain terminals.
• When a voltage signal is applied at the gate terminal, the current starts flowing between the source and drain terminals.

IRF830 Datasheet

Before applying this component to your electrical project, it’s better to go through the datasheet of the component that highlights the main characteristics of the device. You can download the datasheet of this component IRF830 by clicking the link mentioned below.

IRF830 Equivalent

The following are the equivalent of IRF830.

• FTK480
• 8N50
• KF12N50

While working with the alternatives, always check the pinout as the pinout of the alternatives might differ from the pinout of this device.

Taking Care of Your Machines

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through how to take care of your machines. When you own a business, more likely than not, your business has machines or software that occasionally need maintenance. Sometimes these things can happen abruptly and bring a halt to the flow of your business. That is why it is important to know your machines or software well and know when a maintenance job on them is needed. The worst thing that can happen to you and your business is for a machine or software to stop working when you are at your busiest. That can hurt your business.

Knowing Your Equipment

Knowing your equipment inside and out is a huge asset to your company. This will save you both time and money in the long run because you will not have to keep bringing in a repair guy or IT guy to fix your problem. Fewer problems to fix means more time working and bringing in money. If you spend less money on repair people that means more money in profits, which means your wallet will feel a bit heavier. The first thing you can do is when you purchase your equipment, you can take time to learn about it inside and out. That way, if something does go astray, you will know what could be wrong and how to fix it. You may even be able to notice signs of your equipment starting to deteriorate so you can tackle the problem before it becomes a hindrance to you making money. As you know well, money is everything when it comes to business and you do not want to lose any of it.

How You Can Be Prepared For Anything

Being unprepared can be a death sentence for your business. If a machine or software you use daily goes and you are not ready, that is not good. The first thing you can do is make someone come in and do a monthly check-up. Now while this would keep you prepared, it would be very costly, and depending on your budget, it may not be worth it. Something you can take a look at is the fault protection machine learning solution. This will analyze your equipment’s working conditions and predict future failures or problems that may arrive. It is a much cheaper option than having a guy come out routinely and having to check on your equipment. In the end, knowing your business also means knowing the equipment and software you use every day to make your business run. It is not an exciting thing but it is an important one. Being unprepared for equipment or software to fail may not be a death sentence to a company, but it will be a thorn in your side for a long time. The best thing you can do is educate yourself on all your available options. In today’s world, it is becoming more and more likely that your work will be done on some sort of equipment or software. Do not be that business that loses customers because you were unprepared. That’s all for today. I hope you find this article useful. If you have any questions, you can approach me in the section below. I’d love to help you the best way I can. Thank you for reading the article.
