The reverse standoff voltage is 20.5 V, meaning the part is fully non-conducting below that level and begins to avalanche at 22.8 V minimum breakdown. For a 24 V nominal automotive bus that sees transients up to 33 V, the 20.5 V standoff leaves enough margin that the diode does not leak during normal operation but still catches the surge before the downstream IC's abs-max rating. ## Bidirectional channel and temperature envelope A single bidirectional channel protects against positive and negative transients equally — one component for both polarities, saving board space versus two unidirectional diodes back-to-back. ## Surface-mount package and board integration The SMC body is larger than the SMA/SMB siblings, which keeps the junction-to-ambient thermal resistance low enough to sustain repetitive pulse trains without exceeding the 150°C limit. The supplier device package is identical to the case code (DO-214AB), so the PCB land pattern is unambiguous.","metaTitle":"1.5SMC24CAHM3_A/I Vishay TVS, AEC-Q101, 1500W, Bidirectional","metaDescription":"Active Vishay 1.5SMC24CAHM3_A/I bidirectional TVS diode, AEC-Q101 qualified, 1500W peak pulse, 20.5V standoff, DO-214AB.

For a non-automotive BOM, that part is a drop-in substitute. For any automotive line, the A/I suffix is the only acceptable option because the OEM will demand the AEC-Q101 PPAP documentation."},{"question":"What compliance documentation does Vishay provide for 1.5SMC24CAHM3_A/I?","answer":"Vishay General Semiconductor - Diodes Division provides AEC-Q101 qualification reports, PPAP documentation (upon request through the supply chain), RoHS compliance certificates, and REACH SVHC declarations for this part.
