The AEC-Q101 qualification confirms the part was stress-screened to automotive reliability standards for the ambient temperature band it will see inside the engine bay or chassis harness. ## Clamping ceiling and the standoff margin The reverse standoff voltage is 8.55 V typical, and the minimum breakdown triggers at 9.5 V — so the part sits idle on a 12 V rail with comfortable headroom. When a transient arrives, the maximum clamping voltage across the full 103 A peak pulse current is 14.5 V. That 1.7× ratio between standoff and clamping ceiling is the clamping ratio the downstream protected circuit must survive — a sensitive ECU input rated for 16 V absolute maximum will see the transient clamped well below its limit. The 103 A peak pulse current rating at 10/1000 µs is the waveform condition for the 1.5 kW figure; higher-energy transients or slower waveforms derate the available peak power, so the waveform shape matters as much as the headline number when selecting the suppressor for a specific threat profile. ## 175°C junction temperature and automotive duty The DO-201AA axial leadframe gives the die good thermal conduction down the leads to the PCB pad, but board-level thermal design still sets the practical continuous dissipation limit. At elevated ambient, the thermal resistance junction-to-ambient governs how much of that 1.5 kW peak budget converts to a DC derated rating; the datasheet curve is the reference for that conversion, not a simple datasheet table entry. Listed as Active by Vishay General Semiconductor — Diodes Division. The base product number 1N6271 anchors a series, but the specific suffix and AEC-Q101 screening level for the AHE3_A/C variant means any alternate source must be evaluated for the same automotive grade. Sourced to order per BOM quantity against an RFQ; availability and current lead times confirmed at quote time.","metaTitle":"Vishay 1N6271AHE3_A/C TVS Diode, 1500W Peak Pulse","metaDescription":"Vishay 1N6271AHE3_A/C Zener TVS diode, 1500W peak pulse power, AEC-Q101 qualified, DO-201AA axial.
