Ultrafast Hecovery EXPANDING the SWITCHMODE rectifier family are these ultrafast devices with reverse recovery times of 25 to 100 nanoseconds. They complement the broad Schottky offering for use in the higher voltage outputs and internal circuitry of switching power supplies as operating frequencies increase Table 25. Ultrafast Recovery Rectifiers from 20 kHz to 250 kHz. Additional package styles and oper- ating current levels are planned. All devices are connected cathode to case or cathode to heatsink, where applicable. Reverse polarity may be avail- able on some devices upon special request.
