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. ## **Environmental Specifications** **==> picture [244 x 162] intentionally omitted <==** **----- Start of picture text -----**<br> Test Specifications and Conditions<br>MIL-STD-750, M-1040, Cond A Applied Peak<br>AC Blocking<br>AC voltage @ 110°C for 1008 hours<br>MIL-STD-750, M-1051,<br>Temperature Cycling<br>100 cycles; -40°C to +150°C; 15-min dwell time<br>EIA / JEDEC, JESD22-A101<br>Temperature/Humidity 1008 hours; 320V - DC: 85°C; 85%<br>rel humidity<br>MIL-STD-750, M-1031,<br>High Temp Storage<br>1008 hours; 150°C<br>Low-Temp Storage 1008 hours; -40°C<br>Resistance to<br>MIL-STD-750 Method 2031<br>Solder Heat<br>Solderability ANSI/J-STD-002, category 3, Test A<br>Lead Bend MIL-STD-750, M-2036 Cond E<br>**----- End of picture text -----**<br> © 2020 Littelfuse, Inc.
