The single bidirectional channel handles symmetrical clamping on both polarities, which simplifies PCB layout for signal pairs and AC-coupled lines — one device replaces two unidirectional diodes in series. ## DO-214AB footprint and reflow handling Housed in the DO-214AB (SMC) package, the part measures roughly 7.1 mm × 6.2 mm with a 2.6 mm seated height. Standard reflow profiles per JEDEC J-STD-020 work with this package — no special bake or moisture sensitivity precautions beyond the standard MSL level for SMC diodes.","metaTitle":"Vishay 1.5SMC12CAHM3/H TVS, 1500W, 10.2V, DO-214AB","metaDescription":"1.5SMC12CAHM3/H bidirectional TVS diode, 1500W peak pulse, 10.2V standoff, AEC-Q101, DO-214AB.
