UH1PB

The UH1PB 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.

UH1PB has seven features. (1)Very low profile: typical height of 1.0mm. (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)Compliant to RoHS directive 2002/95/EC and in accordance to WEEE 2002/96/EC. (7)Halogen-free according to IEC 61249-2-21 definition. Those are all the main features.

Some absolute maximum ratings of UH1PB  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 1.0A. (3)Its peak forward surge current 10 ms single half sine-wave superimposed on rated load would be 30A. (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 UH1PB are concluded into several points as follow. (1)Its instantaneous forward voltage would be typ 0.88V at If=0.6A, Ta=25°C and would be typ 0.95V and max 1.05V at If=1.0A. (2)Its reverse current would be max 1.0uA at Ta=25°C and would be typ 5.0uA and max 25uA at Ta=125°C. (3)Its maximum reverse recovery time would be typ 19ns and max 25ns at If=0.5A, Ir=1.0A, Irr=0.25A. (4)Its typical softness factor would be typ 0.4. (5)Its maximum reverse recovery current would be typ 3.7A and max 5.5A. (6)Its typical stored charge would be typ 48nC. (7)Its typical junction capacitance would be typ 16pF. And so on.
