The article discusses the function of diode tester which limits reverse voltage to protect sensitive junctions. It states that photodiodes and laser diodes function in ohmeters with reverse-voltage and forward-current ratings of sensitive diodes for different reverse modes. It provides a diagram ...

There are some well known techniques for handling source voltage reversal. The most obvious is a diode from the source to the load, but it has the downside of extra power dissipation due to the diode forward voltage. As elegant as it is, a diode will not work in portable or backup appli...

An epitaxial diode which has a substrate and a high-resistance central zone of one conduction type and an outer zone of the other conduction type and which also has recombination centres for reducing the carrier lifetime and in which high reverse voltage loading capacity is achieved by arranging...
The diode reverse recovery effect of Cockcroft-Walton voltage multiplier circuit is investigated by analysis and circuit simulation. According to the analysis and circuit simulation study, it can be concluded that the multiplier diode reverse recovery problem is mainly caused by the diodes in the ...
I connected the Zener diode in this polarity so that if the 741 output is HIGH, then the Zener diode will break down and determine its Vz voltage in the input of the OR gate so that +VCC=15V won't destroy it. I just wanted to know the current limitation of the Zener in reverse bi...
