25TTS...FP High Voltage Series
Vishay High Power Products
Phase Control SCR
TO-220AB FULL-PAK, 25 A
DESCRIPTION/FEATURES
2
(A)
The 25TTS...FP 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.
The fully isolated package (V
INS
= 2500 V
RMS
) is UL E78996
approved.
Plastic material 94V
Ro
.
This product has been designed and qualified for industrial
level.
