1N4964/TR

Single Zener Diodes Overview

The Microchip Technology 1N4964/TR is a military-qualified, voidless hermetically sealed 5-watt glass Zener diode. It provides an 18V nominal Zener voltage with a standard 5% tolerance at a test current of 65mA. The device features a maximum reverse leakage current of 5µA and a Zener impedance of 4 Ohms. It operates within a temperature range of -65°C to +175°C and utilizes axial leads for through-hole mounting.

Single Zener Diodes Feature Summary

Hermetically sealed voidless-glass construction with internal metallurgical bonds
Military qualification per MIL-PRF-19500/356 for high-reliability applications
Inherently radiation hard design
ESD nonsensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

High-reliability aerospace systems
