The 47.8V reverse standoff voltage is the DC operating level: the part stays transparent below that, only starts clamping when the transient exceeds 53.2V breakdown. For a 48V nominal automotive bus (like a 48V mild-hybrid rail or a 24V truck system with high surge margin), this sits right at the protection threshold. ## AEC-Q101 — the under-hood reliability baseline AEC-Q101 qualification means this diode passed the automotive stress tests: temperature cycling, high-temperature reverse bias, and ESD robustness. The 1.5SMC series is a standard footprint for 1500W TVS diodes in automotive ECU and BMS applications. The DO-214AB package has a visible cathode band on unidirectional parts; on this bidirectional variant, the polarity marking is symmetric — no orientation risk during pick-and-place. ## Package and rework — DO-214AB on the bench DO-214AB (SMC) is a standard surface-mount package with a large tab for thermal transfer. Rework is straightforward with hot air at 260°C for 10 seconds; the package body is moulded epoxy that handles one reflow cycle without moisture sensitivity issues. Tape-and-reel packaging (TR) means it ships on 13-inch reels for automated assembly. The base product number 1.5SMC56 covers the unidirectional and bidirectional variants; the 'CA' suffix in this code confirms bidirectional clamping, and 'HM6G' is the automotive AEC-Q101 grade suffix.","metaTitle":"1.5SMC56CAHM6G TVS Diode, 1500W, DO-214AB, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC56CAHM6G Zener TVS, 1500W peak pulse, 77V clamp, DO-214AB, AEC-Q101 automotive grade.
