SKT491/04E Overview

SCRs have a rated average on-state current (A) that is defined as the maximum repetitive average forward current that can flow through them, and it is rated to be 550.Normal operation should have a peak on-state voltage (V) of [email protected] terms of surge current rating, it specifies the maximum amount of nonrepetitive or surge current that the SCR is capable of withstanding for a limited number of times during its lifespan.Including all repetitions of transient voltage, the repetitive peak reverse voltage is the maximum instantaneous value of reverse voltage.

SKT491/04E Features

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