SxX8xSx Series

Teccor® brand Thyristors

EV Series 0.8 Amp Sensitive SCRs

Description

New device series offers high static dv/dt and lower turn
off (t

) sensitive SCR with its small die planar construction

q

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.
