1N4576A

Single Zener Diodes Overview

The Microchip Technology 1N4576A is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.005 %/°C. It operates at a test current (IZT) of 2.0 mA, featuring a maximum reverse current of 2 µA at 3 V and a dynamic impedance of 50 Ω. The device supports an operating temperature range from -55°C to +100°C and is housed in a hermetically sealed glass DO-7 (DO-204AA) axial-leaded package.

Single Zener Diodes Feature Summary
