classifcation 94V-0| |**Lead Material**|Copper Alloy| ## **Design Considerations** Careful selection of the correct device 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 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, 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. **==> picture [245 x 205] intentionally omitted <==** **----- Start of picture text -----**
