2N1874A Overview

SCRs are rated at 1.25 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 [email protected] SCR's surge current rating is 15, 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.

2N1874A Features

the rated average on-state current is 1.25
the peak on-state voltage (V) should be 2.5@2A
