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.
