T8KC__3203
Phase Control Thyristor
325 Amperes 6500 Volts
Powerex, Inc., 200 Hillis Street, Youngwood, Pennsylvania 15697-1800 (724)925-7272
The T8KC is a high voltage, high current
disc pack SCR employing a high di/dt
gate structure. This gate design allows the
SCR to be reliably operated at high di/dt
and dv/dt conditions in various phase
control applications.
FEATURES:
