The unidirectional single-channel configuration clamps only one polarity; for bidirectional protection on AC or bipolar lines, a pair or a bidirectional variant is needed. No power line protection feature is built in — this is a transient suppressor, not a continuous overvoltage clamp. ## Surface-mount packaging and board integration The SMC footprint is larger than the SMA/SMB siblings, providing better thermal dissipation for the 1500 W pulse rating — the copper pad area under the cathode tab directly influences the junction-to-ambient thermal resistance.","metaTitle":"1.5SMC150AH TVS Diode, 1500W, 128V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC150AH automotive Zener TVS, 1500W peak pulse, 128V reverse standoff, AEC-Q101 qualified.
