The 7.02V standoff and 12.1V clamping ceiling put the working window for a 5V rail at roughly 1.4× nominal — enough headroom for normal operation, fast enough to absorb automotive load-dump and inductive kickback. At 124A peak pulse current it handles the short-duration surge without going into thermal runaway. ## AEC-Q101 qualification — what it means for automotive sourcing AEC-Q101 is the automotive stress test qualification for discrete semiconductors — it verifies the part survives temperature cycling, humidity, and electrical overstress at the severity required for engine-compartment and chassis-domain deployments. The 1.5SMC8.2AHM3/H carries this badge, which is what most Tier-1 automotive ECUs demand before approving a component on the BOM. Telecom applications — the second listed use case — benefit from the same ruggedised transient immunity in outdoor equipment enclosures. ## Thermal margin and the 150°C junction ceiling The minimum breakdown voltage of 7.79V is the cliff where the TVS turns fully on; the 7.02V standoff sits below this, so the diode sits in high-impedance standby under normal rail conditions without leakage-induced rail sag. ## Sourcing posture — active part, standard SMC footprint Active lifecycle per Vishay. The base product number 1.5SMC8.2 is the series anchor — the \"HM3/H\" suffix carries the automotive grade and halogen-free/RoHS-compliant terminal plating. Surface-mount DO-214AB (SMC) is the industry-standard TVS package; the Tape & Reel format suits high-volume assembly.","metaTitle":"Vishay 1.5SMC8.2AHM3/H TVS Diode, 1500W Peak, AEC-Q101","metaDescription":"1.5SMC8.2AHM3/H — 1500W peak pulse TVS diode, AEC-Q101 qualified, DO-214AB SMC. 7.02V standoff, 12.1V clamping, 124A peak.
