The PRX C770 is a high voltage, high current disc
pack SCR employing a high di/dt, distributed gate
structure to optimize turn-on speed. This gate
design allows the SCR to be reliably operated at
high di/dt and dv/dt conditions in inverter
applications to 1KHz operating frequency.
FEATURES:
Fast Turn-Off Time
High di/dt Capability
High dv/dt Capability
Hermetic Ceramic Package
2
Excellent Surge and I t Ratings
