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.
