Design Considerations

Careful selection of the correct device for the application’s

operating parameters and environment will go a long way

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.
