1N3155/TR

Single Zener Diodes Overview

The Microchip Technology 1N3155A/TR is a temperature-compensated Zener diode designed for precision voltage reference applications. It features an 8.4 V nominal Zener voltage with a tight 5% tolerance and operates at a test current of 10 mA. The device exhibits low dynamic impedance of 15 Ohms and minimal reverse leakage current of 10 uA. Packaged in the DO-204AA (DO-7) axial through-hole format, it supports a wide operating temperature range from -65°C to +175°C. With a power dissipation rating of 500 mW and a near-zero voltage temperature coefficient of 0.005%/°C, it ensures stable performance under varying thermal conditions.
