EV Series 0.8 Amp Sensitive SCRs
SxX8xSx Series
Description
New device series offers high static dv/dt and lower turn
off (tq) 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.

Design Considerations
Careful selection of the correct device for the application’s
operating parameters and environment will go a long way
toward extending the operating life of the Thyristor. Good
design practice should limit the maximum continuous
current through the main terminals to 75% of the device
rating. Other ways to ensure long life for a power discrete
semiconductor are proper heat sinking and selection of
voltage ratings for worst case conditions. Overheating,
overvoltage (including dv/dt), and surge currents are
the main killers of semiconductors. Correct mounting,
soldering, and forming of the leads also help protect
against component damage.
