1N3155A/TR

Single Zener Diodes Overview

The 1N3155A/TR is a temperature-compensated Zener diode manufactured by Microchip Technology. It features an 8.4 V nominal Zener voltage with a tight 5% tolerance and a low voltage temperature coefficient of 0.005%/°C. The device operates in the DO-204AA (DO-7) through-hole package, dissipating up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 10 µA and a Zener impedance of 15 Ohms at a test current of 10 mA. It supports a wide operating temperature range from -65°C to +175°C.
