A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

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 ...

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 ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

Although they are usually limited to only two leads, rectifiers and diodes play an important role in power electronic systems. In 2011, many types of rectifier/diodes were introduced, from bridge ...

Nexperia has introduced 120V silicon germanium (SiGe) rectifier diodes “with reverse voltages that combine the high efficiency of their Schottky counterparts with the thermal stability of ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

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 ...

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity ...

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 ...

Vishay Intertechnology VSH unveiled two new 1200 V FRED Pt Hyperfast rectifiers, namely VS-E7MH0112-M3 and VS-E7MH0112HM3c, in its Gen 7 platform. Notably, both devices come in an SMA (DO-214AC) ...
