VS-HFA08TB120STRLP

Single Diodes Overview

The VS-HFA08TB120STRLP is a HEXFRED ultrafast soft recovery diode manufactured by Vishay Semiconductors. It features an 8 A continuous forward current rating and a 1200 V repetitive peak reverse voltage. The device utilizes a D2PAK (TO-263AB) surface-mount package with a base cathode configuration. Electrical characteristics include a maximum forward voltage of 3.3 V at 8 A, a typical reverse recovery time of 28 ns, and a maximum reverse leakage current of 1000 μA at 125 °C. It operates within a junction temperature range of -55 °C to +150 °C.
