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 8.Normal operation should have a peak on-state voltage (V) of 1.6@24A.In 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.
