Design Considerations
Careful selection of the correct device for the application’s
operating parameters and environment will go a long way
UPXBSEFYUFOEJOHUIFPQFSBUJOHMJGFPGUIF5IZSJTUPS(PPE
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.
