Breakdown occurs at 11.4 V minimum, clamping the transient to 16.7 V maximum at the rated 89.8 A pulse current — the protected circuit's absolute-maximum input voltage must exceed 16.7 V to avoid secondary damage. Supplied in DO-214AB (SMC) surface-mount package on tape and reel — the standard footprint for 1500 W TVS diodes, with a copper pad area under the cathode tab that sets the thermal resistance for pulse dissipation. The SMC body is larger than the SMA/SMB siblings; the pad layout on the PCB must match the 0.260-inch body width to keep the solder joint stress within limits during reflow. Target applications include automotive and telecom equipment; the AEC-Q101 grade and 1500 W pulse rating suit it for load-dump and inductive-load transient protection on 12 V vehicle buses.","metaTitle":"Vishay 1.5SMC12CAHM3/I TVS, 1500W, 10.2V, DO-214AB","metaDescription":"Active-production Vishay 1.5SMC12CAHM3/I bidirectional TVS diode, 1500W peak pulse, 10.2V reverse standoff, AEC-Q101 qualified, DO-214AB SMC.
