1N4620/TR

Single Zener Diodes Overview

The Microchip Technology 1N4620/TR is a single Zener diode rated for 3.3 V nominal voltage with ±5% tolerance. It features a maximum power dissipation of 500 mW and operates in the DO-204AH (DO-35) axial through-hole package. The device exhibits a maximum Zener impedance of 1650 Ohms and a maximum reverse leakage current of 3.5 µA at 1.5 V. It supports a wide operating temperature range from -65°C to +175°C junction temperature.

Single Zener Diodes Feature Summary

Provides stable voltage regulation via metallurgically bonded glass construction
Designed for low-level operation at a test current of 250 µA
Engineered for high reliability in military-grade environments

Single Zener Diodes Applications

Military aerospace voltage reference circuits
High-reliability space electronics protection
Precision instrumentation voltage regulation

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required qualification level, as standard commercial versions differ from MIL-PRF-19500/435 qualified variants. Confirm RoHS compliance status, as military specifications often exclude lead-free requirements. Ensure the ordering code explicitly includes the tape and reel designation if automated assembly is required.

Single Zener Diodes Selection Notes

Select this component when a precise 3.3 V reference is needed under extreme thermal conditions up to 175°C. The low test current requirement makes it suitable for battery-powered or low-power applications where minimal quiescent drain is critical. Verify that the 1650 Ohm impedance meets the noise and stability requirements of the target circuit design.

Single Zener Diodes Part Context

This component belongs to the 1N4614-1 through 1N4627-1 series of 500 mW Zener diodes manufactured by Microchip Technology. These devices are constructed using metallurgically bonded glass technology within the DO-35 package. The series is designed to meet rigorous military standards for high-reliability applications requiring stable voltage regulation.
