DESCRIPTION/FEATURES
The 12TTS08S High Voltage Series of silicon controlled
rectifiers are specifically designed for medium power
switching and phase control applications. The glass
passivation technology used has reliable operation up to
125 °C junction temperature.
Typical applications are in input rectification and crow-bar
(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.
This product has been designed and qualified for industrial
level.
