1N4576

Single Zener Diodes Overview

The Microchip Technology 1N4576 is a 6.4 V temperature compensated Zener reference diode housed in a DO-7 (DO-204AA) glass axial-leaded package. It operates at a test current of 2.0 mA with a maximum voltage temperature coefficient of 0.005%/°C and a dynamic impedance of 50 Ohms. The device supports an operating temperature range from -65°C to +175°C, features internal metallurgical bonding, and provides minimal voltage change over broad temperature ranges for precision instrumentation.
