25TTS.. SERIES
Description/Features
The 25TTS.. new 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 (soft
start) and these products are designed to be used
with International Rectifier input diodes, switches
and output rectifiers which are available in identical package outlines.
