The bidirectional channel means the same device clamps positive and negative transients symmetrically — useful on AC-coupled data lines or bipolar supply rails where polarity is not fixed. Operating temperature spans -65°C to 150°C junction, covering the full automotive temperature envelope from cold-crank to engine-bay soak-back. ## DO-214AB SMC package — rework and board-fit Housed in the DO-214AB (SMC) surface-mount package, this TVS has a large copper tab on the cathode side that wicks heat into the PCB copper pour. The package body is large enough to hand-rework with hot air without lifting pads — the key is preheating the board to 100°C before hitting the joint with 350°C air so the solder reflows before the epoxy cracks. Supplied on Tape & Reel, compatible with standard pick-and-place for volume assembly. The orientation mark on the body indicates the cathode band — for a bidirectional part both directions clamp identically, but the band still identifies pin 1 for the reel orientation.","metaTitle":"Vishay 1.5SMC120CAHM3_A/I TVS Diode, 1500W, Bidirectional","metaDescription":"Active Vishay 1.5SMC120CAHM3_A/I Zener TVS, 1500W peak pulse, 102V standoff, AEC-Q101 automotive qualified.
