Product Description
Product Overview
The Littelfuse EV Series Sensitive SCRs are 0.8 Amp devices featuring a small die planar construction for high static dv/dt and lower turn-off time (tq). They are specifically designed for GFCI (Ground Fault Circuit Interrupter) and Gas Ignition applications, offering glass-passivated junctions for long-term reliability and parametric stability. Key advantages include surge current capability, blocking voltage up to 800V, high dv/dt noise immunity, and sensitive gate for direct microprocessor interface.
