1N4576/TR

Single Zener Diodes Overview

The Microchip Technology 1N4576/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.005 %/°C (0.32 mV/°C). It operates at a test current of 2.0 mA, features a maximum reverse leakage current of 2 µA at 3 V, and has a dynamic impedance of 50 Ohms. The device is housed in a DO-7 (DO-204AA) glass axial-leaded package with an internal metallurgical bond and is supplied in tape and reel packaging.
