TCAQ__34
Phase Control Thyristor
3400 Amperes 2800 Volts
The TCAQ 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 I2t Ratings
