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.
