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?

The ubiquitous diode—though you likely have a good understanding of this device, this primer of sorts acts as a quick-read guide, highlighting many of the essentials you need ...

A thermal diode is the heat transfer analogue of an electrical diode: it favours the flow of energy carriers such as photons, phonons or electrons in one direction. Here, the authors demonstrate a ...

A potential difficulty due to diode-turn-on time is that the resultant transitory overshoot voltage across the diode, even when restricted to nanoseconds, can induce overvoltage stress, causing ...

The Model 2520 Pulsed Laser Diode Test System performs electrical characterization of laser diodes in either the chip/bar state or in finished products. According to its manufacturer, the 2520 is ...

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, easy-to ...

Four New Jersey cities have begun testing new street lamps powered by light-emitting diodes. The new LED lamps are expected to reduce energy consumption significantly, have a longer life ...
