MBRF20H90CT

The MBRF20H90CT is designed as one kind of vishay formerly general semiconductor of dual high voltage schottky rectifiers.

MBRF20H90CT has six features. (1)Plastic package has underwriters laboratory flammability classification 94V-0. (2)Dual rectifier construction, positive center tap. (3)Metal silicon junction, majority carrier conduction. (4)Low power loss, high efficiency. (5)Guardring for overvoltage protection. (6)For use in low voltage, high frequency inverters, free wheeling, and polarity protection applications. Those are all the main features.

Some absolute maximum ratings of MBRF20H90CT have been concluded into several points as follow. (1)Its maximum repetitive peak reverse voltage would be 90V. (2)Its working peak reverse voltage would be 90V. (3)Its maximum DC blocking voltage would be 90V. (4)Its maximum average forward rectified current would be 20A for total device and would be 10A for per leg. (5)Its peak forward surge current 8.3ms single half sine-wave superimposed on rated load (JEDEC method) per leg would be 250A. (6)Its peak repetitive reverse current per leg at tp=2s, 1KHz would be 1.0A. (7)Its voltage rate of charge (rated Vr) would be 10000V/us. (8)Its operating junction and storage temperature range would be from -65°C to 175°C. (9)Its RMS isolation voltage (MBRF type only) from terminals to heatsink with t=1 second, RH<=30% would be 4500V with conditions of clip mounting (on case), where lead does not overlap heatsink with 0.110" offset and would be 3500V with conditions of clip mounting (on case), where leads do overlap heatsink and would be 1500V with conditions of screw mounting with 4-40 screw, where washer diameter is <=4.9mm (0.19"). It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics about MBRF20H90CT are concluded as follow. (1)Its maximum instantaneous forward voltage per leg would be 0.77V at If=10A and Tc=25°C. (2)Its maximum reverse current per leg at working peak reverse voltage would be 4.5uA at Tj=25°C and would be 6.0mA at Tj=125°C. And so on.
