S4055R Overview
Current RMS is the average strength of the current without regard to its direction, and the current's RMS current (Irms) is 55A.Electrical, electromagnetic, and electronic devices require a holding current (hypostatic) to remain in the 'ON' state, and the current may be 60mA.Thyristors have a forward voltage of 1.8V, which is the amount of voltage required to get current flowing across a diode.In order to determine the effectiveness of insulation on conductors, leakage current can be measured and its maximum leakage current can be set as 1mA.
S4055R Features
its RMS current (Irms) is 55A
its current can be 60mA
this thyristors has 1.8V forward voltage
its maximal leakage current can be 1mA
