1N4620 Description

Short technical summary and product information.

The 1N4620 is a 3.3V Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 3.3V with a tolerance of ±5%, and a maximum power dissipation of 500mW. The diode has a maximum impedance (Zzt) of 1650 ohms and a reverse leakage current of 7.5 µA at 1.5V.

 

This through-hole device is housed in a DO-204AA (DO-7) axial-lead package, suitable for manual or wave soldering assembly. It operates over a wide temperature range from -65°C to 175°C, making it robust for demanding environments. The forward voltage is 1.1V at 200mA.

 

Typical applications include voltage clamping, shunt regulation, and overvoltage protection in low-power circuits. The 500mW power rating makes it appropriate for low-current voltage reference and regulation tasks.
