UH5JT

The UH5JT is designed one kind of high voltage ultrafast rectifiers for use in high voltage continuous mode power factor correctors (CCM PFC), switching mode power supplies, freewheeling diodes and secondary dc-to-dc rectification application.

UH5JT has seven features. (1)Oxide planar chip junction. (2)Ultrafast recovery time. (3)Soft recovery characteristics. (4)Low switching losses, high efficiency. (5)High forward surge capability. (6)Solder dip 260°C, 40s. (7)Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC. Those are all the main features.

Some absolute maximum ratings of UH5JT have been concluded into several points as follow. (1)Its maximum repetitive peak reverse voltage would be 600V. (2)Its maximum average forward rectified current would be 8A. (3)Its peak forward surge current 8.3 ms single half sine-wave superimposed on rated load would be 60A. (4)Its isolation voltage would be 1500V. (5)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 UH5JT are concluded into several points as follow. (1)Its instantaneous forward voltage would be typ 1.71V at If=2.5A, Ta=25°C and would be typ 2.3V and max 3.0V at If=5.0A, Ta=25°C and would be typ 1.13V at If=2.5A, Ta=125°C and would be typ 1.39V and max 1.8V at If=5.0A, Ta=125°C. (2)Its reverse current would be max 5.0uA at Ta=25°C and would be max 100uA at Ta=125°C. (3)Its maximum reverse recovery time would be max 25ns with conditions of If=0.5A, Ir=1.0A, Irr=0.25A. (4)Its typical softness factor would be typ 0.55. (6)Its typical reverse recovery current would be typ 5.8A and max 7.0A. (7)Its typical stored charge would be typ 140nC. (8)Its typical forward recovery time would be typ 160ns. 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!
