SKT55/12E Overview

This value is the average of the maximum repetitive currents flowing through the SCR over its lifetime, and it is 47.A peak on-state voltage (V) of 1.8@200A is necessary for normal operation.A surge current rating specifies that a SCR can withstand a specific limit of non-repetitive surges during its lifetime, and this rating is 1300.There is a repetitive peak reverse voltage, which is the maximum value of all repetitive transient voltages at the same instant, which amounts to 1200.

SKT55/12E Features

the rated average on-state current is 47
the peak on-state voltage (V) should be 1.8@200A
