Design Considerations

Careful selection of the correct device for the application’s

operating parameters and environment will go a long way

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,

the main killers of semiconductors. Correct mounting,

soldering, and forming of the leads also help protect

against component damage.
