SCRs
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 specically 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.
