C702
Phase Control Thyristor
Powerex, Inc., 200 Hillis Street, Youngwood, Pennsylvania 15697-1800 (724)925-7272
1000 Amperes 3200 Volts
The C702 is a medium voltage, high
current disc pack SCR employing a Bar
gate, amplifying gate structure. This
amplifying gate design allows the SCR to
be reliably operated at high di/dt and
high dv/dt conditions in phase control
applications.
FEATURES:
Low On-State Voltage
High di/dt Capability
High dv/dt Capability
Hermetic Ceramic Package
Excellent Surge and I
