In-Circuit Testing of Diodes and Rectifiers

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

100V GaN transistor will integrate Schottky diode for hard switching

For hard-switched power topologies, Infineon is planning a 100V GaN transistors with a integrated Schottky diode. “Due to the lack of body diode in hard-switching applications, GaN-based topologies ...
