The unidirectional polarity means it sits on the positive rail, shunting the spike to ground when the voltage exceeds the standoff threshold. ## Peak pulse power and clamping — the numbers that matter 1500 W peak pulse (10/1000 µs waveform) is the headline rating — it tells you the diode survives a single transient event of that energy without degradation. At 124 A peak pulse current, the diode conducts hard during the event and the clamp voltage of 12.1 V holds the downstream bus within safe limits for the protected circuit. The protection window runs from 7.02 V reverse standoff (normal operating voltage, no conduction) through 7.79 V minimum breakdown (where the diode begins to conduct) to 12.1 V maximum clamping (the voltage the protected node sees at 124 A peak). A 5 V rail has roughly 2 V of headroom before the diode even starts to turn on. ## Junction temperature and automotive thermal margin AEC-Q101 qualification means the part passed temperature cycling, humidity bias, and surge testing per the automotive stress standard — the test report and PPAP documentation are what your quality team will ask for on an IATF 16949 build. ## Package, mounting, and tape-and-reel packaging DO-214AB (SMC) is a three-terminal J-bend package — the central tab is the cathode (protection node), and the two outer leads are the anode return. The wide metal tab and exposed pad underside carry the thermal path; the landing pattern in the datasheet controls the thermal resistance from junction to board. Shipped on Tape & Reel (TR) — the standard format for automated pick-and-place on automotive SMT lines. Confirm reel count and leader/trailer length against your feeder capacity before the line is released.","metaTitle":"Vishay 1.5SMC8.2AHE3/57T TVS Diode, 1500W Peak","metaDescription":"Vishay 1.5SMC8.2AHE3/57T unidirectional TVS diode, 1500W peak pulse, 7.02V standoff / 12.1V clamp, AEC-Q101 qualified, DO-214AB.
