Reverse Current Leakage

The purpose of a diode in an electrical circuit is to ensure that current is only allowed to flow in the correct direction. In other words, it acts as a conductor in one direction and as an insulator in the other. The reverse current leakage test evaluates this function by applying a reverse-biased voltage to the sample and measuring for any reverse current.

There are three methods of testing, one for AC voltage, one for a steady-state DC voltage, and one for a pulsed DC voltage.
