SK055R Overview
As the RMS current measures the average strength, disregarding the direction, its RMS current (Irms) is 55A.In this device, the repetitive peak off-state voltage is 1000V. This is the maximum voltage allowed across the device.The maximal repetitive reverse voltage (Vrrm) is the maximum voltage that a diode can sustain in reverse-bias mode.In electrical, electromagnetic, and electronic devices, the holding current (hypostatic) is the minimum current needed for an electronic or electrical device to remain on.A thyristor with a 1.8V forward voltage has a forward voltage as high as the voltage needed to flow current across it.
SK055R Features
its RMS current (Irms) is 55A
the repetitive peak off-state voltage of this device is 1000V
its current can be 60mA
this thyristors has 1.8V forward voltage
