Reverse standoff voltage is 10.2 V; breakdown starts at 11.4 V min, and clamping is held to 16.7 V max at Ipp. That 6.5 V window between standoff and clamp means a 12 V nominal rail sees the TVS stay off during normal operation but engage before the downstream IC's abs-max rating. ## Package and board integration DO-214AB (SMC) surface-mount package, also designated SMCJ. The large tab area on the bottom conducts heat into the PCB copper — the thermal impedance depends on the pad size and the number of vias to the inner ground plane. Single bidirectional channel means one device clamps both polarities — no need to series two unidirectional parts. The symmetrical layout saves board space and simplifies the BOM. The 150°C ceiling matches the typical silicon limit for power TVS diodes. Marked as general-purpose application and without power line protection (no internal filter or surge-rated series element), so it is intended for signal lines, low-voltage DC buses, and I/O protection rather than AC mains or high-energy power entry.","metaTitle":"Vishay 1.5SMC12CA-M3/9AT TVS Diode, 1500W, Bidirectional","metaDescription":"Active Vishay 1.5SMC12CA-M3/9AT Zener TVS diode, 1500W peak pulse, 10.2V standoff, bidirectional, DO-214AB.
