3400 Amperes 3600 Volts
The TDK4 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:
Low On-State Voltage
High di/dt Capability
High dv/dt Capability
Hermetic Ceramic Package
Excellent Surge and I
