When a 71.7 A pulse hits the 21.2 V clamp voltage, the part absorbs the energy without failing short; the scorch mark tells you if the upstream source delivered more than the junction can handle. The reverse standoff voltage is 12.8 V, meaning the diode stays off below that rail voltage. Breakdown triggers at 14.3 V minimum, and the clamp voltage maxes at 21.2 V at the rated peak current — a 12 V bus sees no leakage until the transient pushes past the standoff threshold. ## Package, temperature, and board-fit Housed in a DO-214AB (SMC) surface-mount package, the same footprint as the SMCJ suffix parts. The junction temperature range spans -55°C to 150°C, so it handles the thermal cycling of outdoor or engine-bay environments without derating the peak pulse power at the cold end. Single bidirectional channel — one part clamps both polarities, saving a diode and board space compared to back-to-back unidirectional TVS devices. No power line protection built in; this is a signal or low-power rail protector, not a mains-side suppressor. ## Sourcing and compliance Compliance documentation (RoHS, REACH) is maintained by Littelfuse for the 1.5SMC series; the base product number is 1.5SMC for cross-referencing datasheets and PCNs.","metaTitle":"Littelfuse 1.5SMC15CA TVS Diode, 1.5kW, 12.8V Standoff","metaDescription":"Littelfuse 1.5SMC15CA bidirectional Zener TVS, 1500W peak pulse power, 12.8V reverse standoff, DO-214AB SMC.
