What rating is the average on-state current?
It is the average value of a current that is allowed to flow through a thyristor in the forward direction under specified temperature, current waveform and frequency conditions and is the average value in one cycle. Generally, it is the value when a single-phase half wave of 180° is allowed to flow at a commercial frequency of 50/60 Hz. Therefore, the triac does not have this rating.
