Low-Temp Storage
1008 hours; -40°C operating parameters and environment will go a long way MIL-STD-750, M-1056 toward extending the operating life of the Thyristor. Good 10 cycles; 0°C to 100°C; 5-min dwell-
Thermal Shock
design practice should limit the maximum continuous time at each temperature; 10 sec (max) current through the main terminals to 75% of the device transfer time between temperature rating. Other ways to ensure long life for a power discrete EIA / JEDEC, JESD22-A102 semiconductor are proper heat sinking and selection of
