The 7.02 V reverse standoff is the working voltage in normal operation; the 7.79 V minimum breakdown is where the device begins conducting in the reverse direction. Using this diode against a faster 8/20 µs surge (often seen in automotive load-dump profiles) requires checking the peak current and energy capability separately; the datasheet peak pulse current of 124 A at 10/1000 µs is the governing number for that waveform, and the energy let-through at 8/20 µs will be lower because the pulse width is shorter. ## AEC-Q101 qualification and the automotive deployment envelope The AEC-Q101 qualification means this part has passed the automotive stress tests for discrete semiconductors — including high-temperature reverse bias (HTRB), temperature cycling, and humidity testing. The Tj rating of -65°C to 150°C puts it in the upper tier for under-hood applications; the base plate rating, not the ambient, sets the junction temperature limit, so the thermal path from the DO-214AB solder joint to the PCB copper under the cathode tab determines the actual operating margin.","metaTitle":"Vishay 1.5SMC8.2AHM3_A/H Zener TVS Diode, 7.02V Standoff","metaDescription":"Active AEC-Q101 Zener TVS in DO-214AB. 7.02V standoff, 12.1V clamping, 1500W peak pulse.
