Phase Control SCR
TO-220AB FULL-PAK, 25 A
25TTS...FPPbF High Voltage Series
Vishay High Power Products
DESCRIPTION/FEATURES
The 25TTS...FPPbF 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 140 °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. Fully isolated
package (VINS = 2500 VRMS); plastic material 94VRo.
This product has been designed and qualified for industrial
level and lead (Pb)-free (“PbF” suffix).
