Main Features
Features
New 1.5 Amp sensitive gate SCR series offers high static
dv/dt with low turn off time (tq) through small die planar
construction design. All SCR’s junctions are glass-
passivated to ensure long term reliability and parametric
stability.
The Sx02xS EV series is specifically designed for Gas

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.
