The purpose of the test is to check the presence of the component and its correct operation, signalling any anomalies.

The test consists in:

  • inputting a positive current on the TRIAC gate and testing the conduction between anode and cathode
  • inputting a negative current on the TRIAC gate and testing the conduction between cathode and anode
  • checking the non conduction in the absence of the impulse on the gate.
