Good MIL-STD-750 Method 2031 Solder Heat design practice should limit the maximum continuous current through the main terminals to 75% of the device Solderability ANSI/J-STD-002, category 3, Test A rating. Other ways to ensure long life for a power discrete Lead Bend MIL-STD-750, M-2036 Cond E 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.
