S4055WTP Overview
A RMS current describes the average strength of a current, disregarding its direction, and its RMS current (Irms) is 55A.This device's repetitive peak off-state voltage is 400V, which is the maximum peak voltage allowed across the device.In electrical, electromagnetic, and electronic devices, a holding current (hypostatic) is the minimum current required to keep them in the 'ON' state, and it can be 60mA.This thyristor has 1.8V forward voltage, which is the voltage needed to get current flowing across it.Insulation effectiveness can be determined by the leakage current, and its maximum leakage current can be 2mA.
