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 [246 x 191] intentionally omitted <==** **----- Start of picture text -----**<br> Test Specifications and Conditions<br>MIL-STD-750, M-1040, Cond A Applied Peak AC<br>AC Blocking<br>voltage @ 150°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; 160V - 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>Moisture Sensitivity<br>Level 1, JEDEC-J-STD-020<br>Level<br>**----- End of picture text -----**<br> ## **Dimensions — TO-220AB (R-Package) — Non-Isolated Mounting Tab Common with Center Lead** **==> picture [501 x 202] intentionally omitted <==** **----- Start of picture text -----**<br> T C MEA SURING POIN T AREA (REF .) 0. 17 IN [2] Dimension Inches Millimeters<br>O Min Max Min Max<br>E A P 8.13.320 A 0.380 0.420 9.65 10.67<br>MT2 B 0.105 0.115 2.66 2.92<br>C B C 0.230 0.250 5.84 6.35<br>13.36 D 0.590 0.620 14.99 15.75<br>D .526 E 0.142 0.147 3.61 3.73<br>7.01.276 F 0.110 0.130 2.79 3.30<br>G 0.540 0.575 13.72 14.61<br>H 0.025 0.035 0.64 0.89<br>F NO TCH INGA TE LEAD J 0.195 0.205 4.95 5.21<br>TO ID.

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
