At that same surge shape it absorbs a 124 A peak pulse current and clamps to a maximum 12.1 V, while the standoff sits typ at 7.02 V and the minimum breakdown threshold is 7.79 V. The 7.79 V minimum breakdown figure is what sets the protection threshold — the part turns on sharply above that voltage and the 12.1 V clamping ceiling is what the downstream circuit sees during a transient event. For a 7.02 V rail that sees the occasional inductive kick or ESD hit, that window is tight enough to protect sensitive semiconductors without wasting clamp current on normal operation. ## Temperature grade and automotive qualification The AEC-Q101 qualifier means the part has passed the automotive stress-grade qualification sequence — temperature cycling, high-temperature reverse bias, power temperature cycle — making it deployable in safety-critical and powertrain-adjacent circuits where an unmodified commercial-grade TVS is not acceptable. The DO-214AB (SMC) footprint is the standard six-millimeter body for this power class. It mounts surface-mount, with the cathode bar oriented toward the protected rail. The Tape & Reel packaging suits high-volume pick-and-place lines — confirm the reel pitch matches the feeder width before loading. The base product number 1.5SMC8.2 keys into the series voltage selection — the 8.2 V standoff rating is the centre point for this variant, sitting between the lower-standoff and higher-standoff siblings in the same package. The 1.5SMC8.2CAHM3/I is listed Active. For production ramp or multi-year service builds, specify the full BOM quantity and any date-code preference at RFQ so the quote reflects the correct lot profile.","metaTitle":"Vishay 1.5SMC8.2CAHM3/I TVS Diode, 7.02V Standoff, DO-214AB","metaDescription":"Bidirectional TVS diode, 1500 W peak pulse at 10/1000 µs, 7.79 V min breakdown / 12.1 V clamping.
