AEC-Q101 qualification means this part has passed the automotive-grade stress tests — temperature cycling, high-temperature reverse bias, and ESD — required for under-hood and cabin electronics. The minimum breakdown voltage is 25.7 V, so the diode starts conducting just above the 24 V rail's normal regulation band. The maximum clamping voltage of 37.5 V at 42 A peak pulse current limits the transient voltage seen by downstream components — a 24 V-rated ECU input with 40 V abs-max survives this clamp. Bidirectional (single channel) means the same device clamps positive and negative transients symmetrically — no need for two diodes in anti-series on a bipolar signal line or an AC-coupled data pair. Tape-and-reel packaging supports automated pick-and-place assembly.","metaTitle":"1.5SMC27CAH TVS Diode, 1500W, 23.1V, AEC-Q101, DO-214AB","metaDescription":"1.5SMC27CAH bidirectional Zener TVS, 1500W peak pulse, 23.1V standoff, AEC-Q101 automotive grade.
