EV Series 0.8 Amp Sensitive SCRs
SxX8xSx Series
New device series offers high static dv/dt and lower turn
off (t
q
) sensitive SCR with its small die planar construction
design. It is specifically designed for GFCI (Ground Fault
Circuit Interrupter) and Gas Ignition applications. All
SCRs junctions are glass-passivated to ensure long term
reliability and parametric stability.
