This circuit is from a March 1967 Radio Electronics. The circuit applies to general purpose SCRs such as the TIC106, C106 and others. The test is done by increasing the gate voltage to the trigger point.
In the figure we have a high stability voltage reference, providing a voltage of 10 V at the...
