USD635

The USD635 is designed as one kind of power schottky rectifiers which is ideally suited for output rectifiers and catch diodes in high frequency low voltage power supplies.

USD635 has five features. (1)Very low forward voltage. (2)Reverse transient capability. (3)Economical convenient plastic package. (4)Mechanically rugged. (5)50V working voltage at rated temperature. Those are all the main features.

Some absolute maximum ratings of USD635 have been concluded into several points as follow. (1)Its working peak reverse voltage would be 35V. (2)Its DC blocking voltage would be 35V. (3)Its peak repetitive surge voltage would be 42V. (4)Its average repetitive forward current would be 6A. (5)Its peak repetitive forward current rated Vr, square wave 20KHz, 50% duty cycle at Tc=115°C would be 12A. (6)Its non-repetitive peak surge current 8.3ms would be 150A. (7)Its peak reverse transient current would be 1A. (8)Its operating junction temperature would be 150°C. (9)Its storage temperature range would be from -55°C to 150°C. (10)Its thermal resistance junction to case would be 3.0°C/W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of USD635 are concluded as follow. (1)Its maximum instantaneous reverse current would be 5mA with test conditions of Vr=Vrwm and pulse width=400us and duty cycle=1 percent. (2)Its maximum instantaneous reverse current would be 50mA with test conditions of Vr=Vrwm and pulse width=400us and duty cycle=1 percent at Tc=125°C. (3)Its maximum instantaneous forward voltage would be 0.55V at If=6A and would be 0.65V at If=12A and at Tj=125°C it would be 0.48V at If=6A and would be 0.60V at If=12A. (4)Its capacitance would be 1000pF with test conditions of Vr=5V. (5)Its voltage rate of charge would be 1000V/us with test conditions of Vr=Vrwm. And so on.
