Spread the loveDiodes are essential components found in electronic circuits. They allow current to flow in one direction while blocking it in the other. With time and usage, diodes can become ...

The simple Diode and LED Tester presented here costs under £5 to build (including all components, the battery and a cheap case) and will indicate the polarity of almost all types of LED and other ...

The circuit has been constructed to test and measure the voltage rating of zener diodes. To be able to test the voltage rating of a zener diode up to 50 VDC, a small transformer and a single 555 timer ...

Some diode manufacturers caution against using the diode tester function in ohmmeters because it could exceed the reverse-voltage and forward-current ratings of sensitive diodes.

Coherent opens lab to test new laser diode applications 17 Jun 2002 Coherent's Semiconductor Group (CSG) has opened a new commercial applications laboratory to enable customers to see how Coherent's ...

This article evaluates the lifetime of laser diodes using an accelerated test program. Due to the very long lifetime of the laser diode, it is impractical to test it under normal conditions; for this, ...
