1N5273/TR

Single Zener Diodes Overview

The Microchip Technology 1N5273/TR is a single silicon Zener diode designed for voltage regulation applications. It operates in the through-hole DO-35-2 package and dissipates up to 500 mW of power. The device maintains a nominal Zener voltage of 5.6 V with a standard tolerance of 5%. It functions reliably across an extended temperature range from -65°C to +175°C, featuring a maximum reverse leakage current of 5 µA at rated voltage.

Single Zener Diodes Feature Summary
