Phase Control SCR, 70 A
70TPS.. High Voltage Series
Vishay High Power Products
DESCRIPTION/FEATURES
The 70TPS.. High Voltage Series of silicon controlled
rectifiers are specifically designed for high and medium
power switching and phase control applications.
Typical applications are in input rectification (soft start) or
AC-switches or high current crow-bar as well as others
phase-control circuits.
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.
