The cathode band on the body marks the polarity for unidirectional variants; this bidirectional part has no polarity marking, so orientation is free. ## Clamping performance and the 23.1 V standoff rail That clamping ceiling protects downstream components rated for 40 V or higher — a common margin for automotive 24 V systems where load-dump transients can exceed 35 V. ## AEC-Q101 qualification and automotive line fit The 1.5SMC27CAHM3/H carries AEC-Q101 qualification, meaning it has passed the stress tests (temperature cycling, high-temperature reverse bias, and ESD) required for automotive-grade discrete semiconductors. The suffix 'HM3' in the ordering code identifies this as the AEC-Q101 qualified variant with the TransZorb® die construction. The series is listed for Automotive and Telecom applications — the 1500 W pulse capability suits it for suppressing transients on 24 V vehicle power buses, telecom line cards, and industrial control supplies where the 23.1 V standoff matches the nominal rail. The Tape & Reel packaging suits automated pick-and-place assembly. The base product number 1.5SMC27 covers the unidirectional and bidirectional variants; the full ordering code 1.5SMC27CAHM3/H specifies the bidirectional, AEC-Q101 qualified version in the SMC package.","metaTitle":"1.5SMC27CAHM3/H Vishay TVS, 1500W, 23.1V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC27CAHM3/H bidirectional TVS diode, 1500W peak pulse, 23.1V standoff, DO-214AB SMC.
