Powerex-Inc–C702CB

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
