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 ...

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...

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 ...

This file type includes high resolution graphics and schematics. In operation, the LT4320 reads the incoming ac voltage waveform and smoothly turns on the appropriate pair of MOSFETs for each half ...

STMicroelectronics has introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies. ST’s trench Schottky diodes significantly ...

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 ...
