The single-channel Zener construction means it protects one rail per device — no bidirectional clamping, so polarity matters on the PCB layout. The SMC package has a body size roughly 7.1 mm × 6.0 mm, with a typical reflow profile per J-STD-020.","metaTitle":"Vishay 1.5SMC170AHE3/57T TVS, 1500W, 234V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC170AHE3/57T Zener TVS, 1500W peak pulse, 234V clamp, AEC-Q101 qualified.
