3.3 kV Dual Fast Recovery Diodes Feature Isolated Mountings

The QRD3310001, QRC3310001, QRD3310002, and QRC3310002 dual fast-recovery diode modules specify a blocking voltage of 3.3V, maximum fast recovery time of 1.2 µs, and an isolation voltage of 6 kV. Options include a choice of standard dual or common cathode configurations and aluminum nitride or alumina isolation materials. The QRD3310001 and QRC3310001 with aluminum nitride isolation handle 86A at 80°C while the QRD3310002 and QRC3310002 specify 60A at 80°C, also with aluminum nitride isolation. Viable applications include switching power supplies, inverters, choppers, welding power supplies, free wheeling diodes, and high frequency rectifiers. POWEREX, INC., Youngwood, PA. (800) 451-1415.
