Phase Control SCR, 25 A

25TTS... High Voltage Series

Vishay High Power Products

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.
