1N5817 Schottky Diode Datasheet, Pinout, Features and Applications
Hi Guys! I welcome you on board. Glad to see you around. Thank you for clicking this read. In this post today, I’ll detail the Introduction to 1n5817.
The 1n5817 is a Schottky diode used in extremely fast switching applications and carries high forward surge capability and low forward drop voltage. It is available in the DO-201AD package and can do high-frequency operations.
Read this post till the end as I’ll discuss the complete introduction to 1n5817 covering the datasheet, pinout, features, and applications of this component.
Let’s get started.
Introduction to 1N5817
- The 1n5817 is a Schottky diode, also known as a hot-carrier diode, used in extremely fast switching applications.
- It comes in the DO-201AD package and contains low forward drop voltage and high forward surge capability.
- In some applications, less power dissipation is required, in that case, MOSFETs are used in place of Schottky diodes.
- Schottky diode is also known as a hot-carrier diode due to the low electronic energy it exhibits in an unbiased condition.
- This low energy develops the barrier that blocks the movement of electrons. This formation of the barrier is the reason Schottky diodes are also known as hot-carrier diodes.
- Both Schottky diode and regular diode are the same in terms of current flow i.e. both allow current flow in one direction only and blocks it in the opposite direction.
- But these diodes are different when it comes to the voltage needed to turn on these diodes. Both diodes get 2V DC source voltage, but the Schottky diode needs only 0.3V, where 1.7V is left behind to power up the diode. And normal diode needs 0.7V, where 1.3V is left out to power up the diode.

1N5817 Pinout
The following figure represents the pinout diagram of the 1n5817 Schottky diode.
- This power diode comes with two terminals known as anode and cathode. Both terminals are used for the external connection with the electrical circuit.
- The anode side is positive and the cathode side is negative. The current enters the diode from the anode terminal and it leaves the diode from the cathode terminal.
- And current flows from the anode terminal to the cathode terminal. The diode only allows the current flow in one direction only i.e. from anode to cathode. It blocks the current flow from the cathode to the anode terminal.
1N5817 Features
- Exhibits small conduction losses.
- 1n5817 is highly efficient.
- Well protected against overvoltage.
- Used in extremely fast switching.
- Available in package DO-201AD.
- Contains high surge capability.
- Contains low forward drop voltage.
1n5817 Schottky Diode Construction
- The 1n5817 is constructed when the semiconductor material is mixed with the metal that creates the barrier.
- When the metals like chromium, platinum, tungsten, and molybdenum are combined with the n-type semiconductor material, it results in the formation of Schottky diode. The n-type semiconductor is the material where electrons operate as a major charge carriers and holes work as minority carriers.
- The Schottky diode contains two terminals called anode and cathode. The anode side is positive that is composed of metal material and the cathode side is negative that is made-up of semiconductor material. The current flows from the positive anode metal side to the cathode negative semiconductor side. Plus, the current enters the diode from the anode side and it leaves the diode from the cathode terminal.
- Both n-type and p-type semiconductor material can be used to work as a cathode terminal in Schottky diode, but n-type materials are preferred over p-type material because the later comes with low drop voltage.
- The forward drop voltage of the Schottky diode main depends on the nature of metal and semiconductor material used to form the barrier.
1N5817 Applications
- Incorporated in sample-and-hold circuits.
- Used in high-frequency and low voltage inverters.
- Employed in polarity protection and DC/DC converters applications.
- Used in freewheeling and logic circuits.
- Used for signal detection and extremely fast switching applications.
- Incorporated in solar systems.
- Used to control the electronic charge.
- Employed in radio frequency applications.

LM2575 Buck Converter Datasheet, Pinout, Features, Applications
Hi Guys! Glad to see you around. I welcome you on board. In this post today, I’ll walk through the Introduction to LM2575.
LM2575 is a step-down voltage regulator mainly used to step down the voltage. It is also known as a buck converter and is used to drive load under 1A. In the customized output version of the buck converter, you can set the output voltage as you like better. It comes with an extremely good load and line regulation and is available in fixed output voltages with 3.3V, 5V, and 12V.
I suggest you read this post all the way through, as in this post I’ll detail the Introduction to LM2575 covering the datasheet, pinout, features, and applications of this component LM2575.
Let’s get started.
Introduction to LM2575
- LM2575 is a voltage regulator and simplified version of switching power supplies that carry all functions required to step down the voltage in the circuit.
- This buck converter is incorporated with an integrated switch that can support load under 1A.
- LM2575 carries an excellent load line and load regulation. It comes in two versions: fixed output voltage version with voltage 3.3V, 5V, 12V, and adjustable output version that gives the ability to pick your desired output.
- It is also called the DC-to-DC power converter employed to step down the voltage from its input supply to its output load. The current increases during this voltage regulation.
- This regulator is integrated with a fixed-frequency oscillator of about 52 kHz and an in-built frequency compensation method.
- Frequency compensation is applied to reduce vibration and oscillation in the circuit. It can be obtained using resistance-capacitance networks.
- Apart from the remarkable load and line regulation, this device comes with a manual shutdown option through an external ON/OFF pin.
- Less external components are needed for this buck converter since it works at a fixed frequency of 52 kHz.
LM2575 Features
- Fixed versions with 3.3-V, 5-V, 12-V, and adjustable output versions
- Adjustable output version with voltage range: 1.2-V to 37-V ±4% maximum over load and line conditions
- Available in two packages named TO-263 and TO-220 packages.
- Can drive load under 1A.
- Comes with low power standby mode, commonly less than 200 µA.
- Uses easily available standard inductors and is highly efficient.
- 4.75 to 40 V is the input voltage range.
- 23V to 37V is the output voltage range.
- 80% efficiency.
- Excellent load and line regulations.
- Fixed internal oscillator frequency of 52 kHz.
- TTL shutdown capability.
- Protection against overcurrent and thermal shutdown.
LM2575 Pinout
LM2575 comes with five terminals.
The following figure shows the pinout diagram of LM2575.
ON/OFF = I = this terminal can shut down the voltage regulator circuit with input supply current decreasing to 50uA. Its working is simple and straightforward.
When the voltage available on this pin is turned below the threshold voltage of 1.3V, it results in turning on the voltage regulator.
And when the voltage is turned above the 1.3V, it results in turning off the voltage converter. You can remove this shutdown feature by connecting the pin to the ground or leaving it open. In both cases, the regulator will be turned ON.
VIN = I = this is the 16 number input terminal attached with the input bypass capacitor to reduce voltage transients and to provide the switching current.
Output = O = this is the 3 number pin that acts like an internal switch where voltage switches between (Vin – Vsat) and -0.5V. The duty cycle on this pin is Vout/Vin. The PCB copper area connected to this pin is mainly used to reduce the coupling.
Ground = three pins number 5,12 & 13 are attached to the ground.
Feedback = I = this is the 7 number pin that indicates the regulated output voltage for the feedback loop.
