Rectifier diode is a kind of device changing AC to DC and has anode and cathode two sides, widely applicable in fields of high power drive, high power rectifiers, non-conotrollable and half-controllable rectifiers. The disc type rectifier diode is characterized by high mean current, low forward voltage drop and double-side cooling, matching with various air-cooling or water-cooling radiators. At present, the high power diode is up to 10000A and voltage can reach 8500V. The stud type, is a kind of device changing AC to DC and has anode and cathode two sides, widely applicable in fields of battery chargers, converters, power supplies, welding machines & motor controls etc. The stud type rectifier diodes are mainly improved from I.R & Semikron and apart from them, the Russian-style diodes, avalanche diodes are developed successfully,too. The metal stud structure and ceramic-metal stud structure both are available and characterized by high surge current capability. Its current is up to 500A.
 

Note:
IGT,VGT,IH are test values under 25ºC . Unless otherwise specified,other parameters in the parameter table are test values under Tjm.
I²t=I²TSM×tw/2:tw=bottom width of half-sinusoid current. Under 50Hz,I²t=0.00512TSM(A²S)
When working under the current of 60 Hz:ITSM(8.3ms)=ITSM(10M=ms)×1.066,Tj=Tjm I²t(8.3ms)=I²t(10ms)×0.943,Tj=Tjm
Gate lead: white or colorless,cathode lead (if necessary): red
