9. Design Considerations
Careful selection of the correct component for the
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.
