1N4575A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4575A/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.01%/°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 is housed in a DO-7 (DO-204AA) glass axial-leaded package and supports tape-and-reel packaging via the TR suffix.
