Vishay VS-16TTS08S-M3, Thyristor 800V, 10A 60mA

The Vishay 16TTS high voltage series of silicon controlled rectifier are specifically designed for medium power switching and phase control applications. Typical applications are in input rectification (soft start) and these products are designed to be used with Vishay HPP input diodes, switches and output rectifiers which are available in identical package outlines.

Maximum average on-state current 10 A
operation temperature - 40 to 125°C

Thyristors - Vishay Semiconductor

A Thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as bistable switches, conducting when their gate receives a current trigger, and continue to conduct while they are forward biased. Thyristors are synonymous to Silicon-Controlled Rectifier (SCR).
Encapsulated modules with electrically isolated base plate. Suitable for applications such as battery chargers, welders and plating equipment, regulated power supplies and temperature and speed control circuits.
