SKT551/12E Overview

SCRs are rated at 550 rated average on-state current (A), which is the maximum repetitive average forward current that can flow through them.Normal operation requires a peak voltage (V) of 1.65@1500A.An SCR's surge current rating is 9000, which specifies the maximum amount of non-repetitive current it can withstand during its life span.In this case, the repetitive peak reverse voltage is the maximum instantaneous value of the reverse voltage, including all repetitive transient voltages.

SKT551/12E Features

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