Description/Features
The 25TTS..S
SAFE
IR
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 identical
package outlines.
