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 ...

Performing single-point pass/fail DC tests on packaged diodes is critical to ensure compliance with manufacturers’ specifications and weed out defective devices before they are shipped. Most types of ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

Ideal diode bridge controller for 9 V to 72 V systems replaces each of the four diodes in a full-wave bridge rectifier with a low loss N-channel MOSFET. The LT4320 from Linear Technology is an ideal ...

The most demanding component in terms of high-frequency operation on an RF-ID tag is the rectifying device: this device needs to be able to charge a storage capacitor providing quasi-d.c. power supply ...

Alpha and Omega Semiconductor has announced a family of active diodes which can reduce the 1.2V forward drop of 600V bridge rectifiers. “Both products are self-powered from the AC line and do not ...
