25TTS..S SERIES
SURFACE MOUNTABLE
PHASE CONTROL SCR
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擄 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.
