Design Considerations
Careful selection of the correct component 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 component 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.
