8TQ100

Overview

The Vishay 8TQ100 is a single silicon Schottky rectifier designed for surface-mount applications in the D2PAK-3 (TO-263-3) package. It features an 8 A average forward current rating and a 100 V repetitive peak reverse voltage. The device exhibits a maximum forward voltage of 880 mV at rated current and supports an 850 A non-repetitive surge current. Operating junction temperatures range from -55°C to +175°C, with a typical reverse leakage current of 550 µA.

Feature Summary

• Utilizes silicon Schottky technology for low forward voltage drop and high switching efficiency.
