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.
