For a BOM line that calls out this exact part number, sourcing now runs through independent distribution channels — surplus inventory, overstock, or broker-held stock. Availability and pricing are lot-specific and confirmed at quote time. ## 1500 W peak pulse — what it protects That 1.5 kW rating means it can absorb a significant energy transient — a lightning surge or inductive load dump — without failing short. The reverse standoff voltage is 11.1 V, so this diode sits across a 11 V or 12 V rail and stays out of the circuit until a transient pushes the line above its 11.75 V minimum breakdown voltage. Clamping is specified at 19.11 V maximum when the peak pulse current hits 83.5 A. Housed in a DO-214AB (SMC) surface-mount package, also referred to as the SMCJ footprint. This is a standard JEDEC outline for TVS diodes in this power class — the two-pad layout is shared across multiple manufacturers, so a board designed for a Vishay or ON Semiconductor SMC part will accept this Littelfuse device. Power line protection is not supported — this is a unidirectional device for DC rail clamping, not AC mains.","metaTitle":"1.5SMC13 Littelfuse TVS Diode, 1500W, 11.1V Standoff","metaDescription":"Littelfuse 1.5SMC13 Zener TVS diode, 1500W peak pulse power, 11.1V reverse standoff, DO-214AB SMC.
