For a BOM line that depends on this exact part, the supply path runs through independent distribution — surplus and new-old-stock inventory sourced per RFQ. The 10.2 V reverse standoff voltage means the part stays high-impedance below that rail level; breakdown starts at 11.4 V min, clamping the surge at 16.7 V max while shunting 90 A peak pulse current. Single unidirectional Zener channel in a DO-214AB (SMC) surface-mount package. Operating temperature spans -65°C to 150°C junction, so it suits outdoor or under-hood environments where ambient heat and transient stress overlap. ## Board-fit and application context Surface-mount on a standard SMC footprint — the DO-214AB body is the same as other 1.5SMC-series parts, so a common pad layout serves the whole family. General-purpose application class; no power-line protection rating (not intended for AC mains clamping).","metaTitle":"1.5SMC12AT3G Littelfuse TVS, 1500W, 10.2V Standoff, DO-214AB","metaDescription":"Littelfuse 1.5SMC12AT3G Zener TVS diode, 1500W peak pulse, 10.2V reverse standoff, DO-214AB SMC.
