An OEM auditor will expect PPAP documentation for this grade — the AEC-Q101 mark confirms the part passed the required reliability screens (temperature cycling, HTRB, H3TRB, ESD) for automotive-grade deployment. ## Clamping and peak pulse — the ratings that decide fit The 25.3 A peak pulse current (Ipp) at that waveform tells you the diode can absorb a substantial surge without failing — critical for load-dump and inductive kickback protection on an automotive 12 V or 24 V bus. A single unidirectional channel, so it protects one rail. For a dual-polarity supply or an AC-coupled line, you would need a bidirectional or back-to-back pair.","metaTitle":"1.5SMC43AHM3_A/I Vishay TVS, AEC-Q101, 59.3V Clamp","metaDescription":"Active Vishay 1.5SMC43AHM3_A/I TVS, AEC-Q101 qualified, 1500W peak pulse, 36.8V standoff, DO-214AB.
