Thyristors EV Series 0.8 Amp Sensitive SCRs S8X5ECSx RoHS Description The S8X5ECSx offers a high static dv/dt with a low turn off (tq) time. It is specifically designed for GFCI (Ground Fault Circuit Interrupter) and AFCI (Arc Fault Circuit Interrupter), RCD (Residual Current Device) and RCBO (Residual Current Circuit Breaker with Overload Protection) applications. All SCR junctions are glass-passivated to ensure long term reliability and parametric stability.
