Demonstrating the effect of dv/dt turn-on in a Thyristor.
For a Thyristor or SCR in the non-conducting state -
even with the gate tied to the cathode - as the rate
of change of voltage (dv/dt) across the anode and
cathode terminals exceeds the datasheet specified
maximum value (in this case 30V/us), the device will
A similar effect occurs in Diacs and Triacs.

As usual, we can check an SCR with a plain multimeter. But it is not easy. The Simple SCR tester circuit diagram is very useful. We can know the location pin on the gate lead, anode lead and cathode lead. And can also test diode, LED and Triac.The SCR devices kind, when taken to an application with DC voltage.
