Features:Westcode is recognised as the Worldwide leader in distributed gate technology. These devices are available with blocking voltages to 4.5kV and currents to 4kA, with tq from 10 to 300 micro seconds. The unique distributed gate design and lifetime control features give these devices both high di/dt capability and fast, low recovery turn-off, while maintaining a low on-state voltage drop. Ideally suited to application including: induction heating, power supplied, high frequency inverters/converters, UPS and pulse power.Except the brand above we can also provide the other brands as follows:Vishay RectifierAlphaEmersonTycoHindBOSCHEltekEmerson rectifier Sanrex rectifierDenso rectifier Yamaha rectifier Suzuki rectifier Schottky rectifier Benning RectifierShindengen RectifierEaton RectifierIR RectifierGE RectifierABB RectifierMitsubishi RectifierSemikron RectifierJieJie MicroelectronicsWXDH ThyristorTechele ThyristorXunfo ThyristorNXP ThyristorRenesasLiujing ThyristorZhongLi ThyristorLittelfuse ThyristorNell ThyristorST ThyristorON SemiconductorSanRexXFKKJ thyristorSZGKTIXYS thyristorMitsubishi thyristorWestcode thyristorPRX thyristorEupec thyristor AEG thyristorPowerex thyristorABB thyristorInfineon thyristorGE thyristorToshiba thyristorVishay thyristorSemikron thyristorShould you have any questions please feel free to ask us.
