The bidirectional configuration (single channel) clamps both positive and negative transients symmetrically, which suits AC-coupled signal lines or power rails that see reverse polarity events. The cathode band is marked on the body; for the bidirectional version the marking is symmetric and orientation does not matter. The surface-mount package reflows on standard lead-free profiles with a 260°C peak. The tape-and-reel packaging (TR suffix) ships in 7-inch or 13-inch reels depending on quantity; the reel quantity is not specified here but the standard for SMC is typically 850 or 3000 pieces per reel. This part can be specified into new designs without obsolescence risk, and the AEC-Q101 qualification means it is production-released for automotive OEM programs.","metaTitle":"1.5SMC56CAHE3/57T Vishay TVS Diode, 1500W, 47.8V Standoff","metaDescription":"Vishay 1.5SMC56CAHE3/57T bidirectional Zener TVS, 1500W peak pulse, 77V clamp, AEC-Q101 automotive grade.
