UH2B

The UH2B is designed as one kind of surface mount ultrafast rectifiers for use in secondary rectification and freewheeling for ultrafast switching speeds of ac-to-ac and dc-to-dc converters in high temperature conditions for both consumer and automotive applications.

UH2B has seven features. (1)Low profile package. (2)Ideal for automated placement. (3)Oxide planar chip junction. (4)Ultrafast recovery times for high frequency. (5)Meets MSL level 1, per J-STD-020, LF maximum peak of 260°C. (6)Solder dip 260°C, 40s. (7)Compliant to RoHS directive 2002/95/EC and in accordance to WEEE 2002/96/EC. Those are all the main features.

Some absolute maximum ratings of UH2B have been concluded into several points as follow. (1)Its maximum repetitive peak reverse voltage would be 100V. (2)Its maximum average forward rectified current would be 2.0A. (3)Its peak forward surge current 8.3ms single half sine-wave superimposed on rated load would be 50A. (4)Its operating junction and storage temperature range would be from -55°C to 175°C. It should be noted that stresses above those values listed in the absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of  UH2B are concluded into several points as follow. (1)Its instantaneous forward voltage would be typ 0.79V at If=1.0A, Ta=25°C and would be typ 0.87V and max 1.05V at If=2.0A, Ta=25°C. (2)Its reverse current would be max 2.0uA at Ta=25°C and would be typ 10uA and max 50uA at Ta=125°C. (3)Its maximum reverse recovery time would be typ 15ns and max 25ns with conditions of If=0.5A, Ir=1.0A, Irr=0.25A. (4)Its typical reverse recovery time would be typ 20ns and max 35ns. (5)Its typical softness factor would be typ 0.3. (6)Its typical reverse recovery current would be typ 5.0A anx max 6.0A. (7)Its typical stored charge would be typ 55nC. (8)Its typical junction capacitance would be typ 42pF. And so on. If you have any question or suggestion or want to know more about this IC please contact us for details. Thank you!
