SKT491/12E Overview

In an SCR, the rated average on-state current (A) is the maximum repeated average value of forward current that can flow through the device, and it is 550.During normal operation, the peak on-state voltage (V) should be [email protected] with surge current ratings of 9000 can withstand peak non-repetitive or surge current during a limited number of cycles during their lifespan.Repeated peak reverse voltage equals the maximum amount of reverse voltage within an instantaneous period of time, including any repetitive transient voltages. It is 1200 V.

SKT491/12E Features

the rated average on-state current is 550
the peak on-state voltage (V) should be 1.65@1500A
