Description/Features

The 25TTS..S new series of silicon controlled

rectifiers are specifically designed for medium

power switching and phase control applications.

The glass passivation technology used has reli-

able operation up to 125° C junction temperature.

Typical applications are in input rectification (soft

start) and these products are designed to be used

with International Rectifier input diodes, switches

and output rectifiers which are available in identi-

cal package outlines.
