Do not exceed 28 C Physical Specifications Terminal Finish Body Material Lead Material Design Considerations % Matte Tin-plated UL Recognized epoxy meeting flammability rating V- Copper Alloy 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.
