VS-16RIA120

Scrs Overview

The VS-16RIA120 is a medium power phase control thyristor from the Vishay VS-16RIA series, rated for a maximum repetitive peak off-state voltage of 1200 V. It features an average on-state current of 16 A at a case temperature of 85 °C and a maximum RMS on-state current of 35 A. The device utilizes a TO-48 (TO-208AA) stud package with a 1/4"-28UNF-2A thread. Key electrical characteristics include a maximum on-state voltage of 1.75 V, a gate trigger current of 60 mA at 25 °C, and a typical turn-off time of 110 μs. Operating junction temperatures range from -65 °C to +125 °C.
