1n4734 Zener Diode Datasheet, Pinout, Features & Applications

Hi Folks! I hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to 1n4734.

The 1n4734 is a silicon planner power Zener diode that is employed as a low current voltage regulator. It is incorporated as a shunt regulator in many applications. This Zener diode conducts the current in both directions in contrast to the regular diode that conducts in one direction only i.e. regular diode conducts in forward biased condition only. This Zener diode conducts in both conditions forward biased condition and reverse biased condition. Power dissipation in this Zener diode is 1W and standard Zener voltage tolerance is ±10%.

I suggest you read this entire post till the end, as I’ll detail the complete Introduction to 1n4734 covering datasheet, pinout, main features, and applications. Let’s dive in.

Introduction to 1N4734

  • The 1n4734 is a Zener diode employed as a low-current voltage regulator. It is also employed in clipping circuits with high power ratings. This Zener diode is made of semiconductors and is used in voltage protection circuits.

  • The current flows from the anode side to the cathode side in the regular diode in a forward-biased condition. On the other hand, in the case of the Zener diode, current conducts in both conditions i.e. forward biased condition and reverse biased condition. Forcing regular diodes to conduct in both conditions will damage the device.
  • The Zener diode is normally used in modern electronics and is constructed by plenty of different voltages.
  • While picking the Zener diode there are two parameters that you should consider… one is the power dissipation and the other is the power Zener voltage. When a higher reverse voltage is applied to the Zener device it creates the Zener voltage.
  • Some Zener diodes experience sharp and highly doped p-n junction when they undergo a Zener effect or Clarence Zener.
  • The power dissipation inside the Zener diode is used to identify the amount of current flow. More power dissipation results in more current flow. Power dissipation in this Zener diode is 1W.
  • Zener diodes are utilized to generate low-power supply rails using higher voltages. Reference voltages in the electrical circuits are also produced by these Zener diodes.
  • In some electrical circuits, there is a limit to the applied voltage. The voltage applied above this limit can damage the device. These Zener diodes are used in those circuits to prevent circuits from overvoltage.

Introduction to 1n4734A Zener Diode Datasheet, Pinout, Features & Applications

Hey Guys! Hope you’re well today. Happy to see you around. In this post today, I’ll detail the Introduction to 1n4734a.

The 1n4734a is a Zener diode used as a low-current voltage regulator. It is composed of silicon material and is employed as a shunt regulator in many applications. This Zener diode conducts the current in both directions in contrast to a normal diode that conducts in one direction only i.e. conducts in forward biased condition only.

I suggest you read this post all the way through, as I’ll be discussing the datasheet, pinout, features, and applications of 1n4734a. Let’s jump right in.

  • The 1n4734a is a Zener diode used in clipping circuits with a high power rating.
  • It comes in the DO-41 package and is used as a low-current voltage regulator in many applications.
  • This Zener diode is composed of semiconductor material and is employed in voltage protection circuits.
  • The current flows from the anode terminal to the cathode terminal in the normal diode in a forward-biased condition. While in the case of the Zener diode, current conducts in both conditions i.e. reverse biased condition and forward biased condition.

  • We cannot force a normal diode to conduct in both directions, if we do so, it will damage the component.
  • The Zener diode is considered as a building block of modern electronics and is manufactured by plenty of different voltages.
  • Two parameters are important to consider while selecting the Zener diode. The power Zener voltage and power dissipation. The Zener voltage is obtained when a higher reverse voltage potential is applied to the Zener diode.
  • Inside the Zener diode, the amount of current flow is evaluated by the power dissipation. More dissipation means more current flow. Power dissipation in this 1n4734a Zener diode is 1300mW.
  • Zener diodes are used to produce low-power supply rails with the use of higher voltages. For electrical circuits, reference voltages are also generated by these Zener diodes.
  • In circuits where there is a possibility of damage to the circuit due to high voltage, these Zener diodes are employed to keep circuits from overvoltage.
  • Some Zener diodes undergo a Zener effect or Clarence Zener where it experiences highly doped and sharp p-n junction and in this case reverse conduction inside the Zener diode is performed by the electronic quantum tunneling which is known as Zener effect.
