(A)
DESCRIPTION/FEATURES
The 25TTS... High Voltage 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 Vishay HPP
input diodes, switches and output rectifiers which are
available in identical package outlines.
This product has been designed and qualified for industrial
level.
