Description/Features
The 25TTS..FP SAFEIR 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.
