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.
