ABSTRACT:
A tester is provided in which a test signal having a selected polarity and magnitude is applied across the main electrodes of a device under test. In the case of an SCR device under test, for example, pulses of a predetermined energy level and polarity are applied to the gate electrode to trigger the SCR into conduction. The tester operates to identify the anode and cathode terminals of the conducting device, as well as to determine without destructive failure of the device under test whether the device is open, shorted or exhibiting leakage.
