AEC-Q101 qualification certifies this part for automotive stress levels — temperature cycling, high-temperature reverse bias, and humidity bias — so it meets the reliability requirements of under-hood and cabin electronic modules. That clamping voltage sits well below the 40V absolute-maximum rating typical of downstream 24V-rated ICs and modules, giving the TVS first-line transient suppression without adding a secondary clamp. The unidirectional Zener structure means this diode conducts only on positive overvoltage events — negative transients are blocked by the forward-biased junction. For bidirectional protection on AC-coupled or floating lines, two devices in anti-series are needed. At 150°C junction, derate the peak pulse power per the manufacturer's curve — the 1500W rating is at 25°C. ## DO-214AB SMC footprint and supply posture Supplied on Tape & Reel for automated pick-and-place assembly. The base product number 1.5SMC27 identifies the voltage variant; the 'A' suffix denotes a 5% tolerance on breakdown voltage, and 'HR7G' encodes the automotive grade and packaging code.","metaTitle":"1.5SMC27AHR7G TVS Diode, 1500W, 23.1V Standoff, AEC-Q101","metaDescription":"Active 1.5SMC27AHR7G Zener TVS diode, 1500W peak pulse, 23.1V reverse standoff, AEC-Q101 automotive qualified.
