USD7520

The USD7520 is designed as one kind of schottky barrier power rectifiers which is specifically to be used as output rectifiers and catch diodes for 3V power supplies. The microsemi high conductivity design, using a heavy copper top post and 4 point crimp, ensures cool thermal operation and low dynamic impedance. Rugged design absorbs stress that can damage glass-to-metal seal during installation and use.

USD7520 has seven features. (1)Extremely low forward voltage (0.425V at 60A, 125°C). (2)High efficiency for low voltage supplies (3V types). (3)Low recovered charge. (4)Rugged package design (DO-5). (5)Low thermal resistance (0.7°C/W). (6)High surge current 1000A. (7)Low reverse current 150mA at rated Vr at 125°C. Those are all the main features.

Some absolute maximum ratings of USD7520 have been concluded into several points as follow. (1)Working peak reverse voltage would be 20V. (2)DC blocking voltage would be 20V. (3)Its peak repetitive surge voltage would be 24V. (4)Peak repetitive forward current would be 150A. (5)Its average rectified forward current would be 75A. (6)Its non-repetitive peak surge current 8.3ms would be 1000A. (7)Its peak reverse transient current would be 2A. (8)Its storage temperature range would be from -55°C to 200°C. (9)Its operating junction temperature would be 175°C. (10)Its thermal resistance junction to case would be 0.7°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 USD7520 are concluded as follow. (1)Its maximum instantaneous reverse current would be 20mA. (2)Its maximum instantaneous forward voltage would be 0.425V at If=60A and would be 0.450V at If=75A and would be 0.550V at If=150A. (3)Its maximum capacitance would be 5000pF at Vr=5.0V. (4)Its maximum voltage rate of charge would be 1000V/us. And so on. If you have any question or suggestion or want to know more information of USD7520 please contact us for details. Thank you!
