S4040R Overview

The RMS current is a measure of the average strength of the current, disregarding its direction. Its RMS current (Irms) is 40A ohms.During the 'ON' state, the holding current (hypostatic) can be 60mA, as it is the minimum current which must pass through a circuit for it to stay in the 'on' state.As this thyristor has 1.8V forward voltage, no current flows across it.Detecting leakage current on conductors can be an indication of insulation effectiveness, and its maximum leakage current can be 0.01mA.
