Product details

1500 W peak pulse — the clamp that defines the protection window

The SMCJ11A-13: That 1.5 kW rating means it can absorb a single high-energy surge — a lightning-induced transient or inductive load dump — without failing short, as long as the energy stays within the pulse derating curve. A 12 V supply rail sees no leakage at steady state; the TVS only clamps when the transient pushes the rail above the breakdown threshold. Single unidirectional channel — one TVS protects one rail. For a bipolar or AC line, two devices back-to-back or a bidirectional variant would be needed.

DO-214AB SMC — the board-fit footprint for 1.5 kW dissipation

Housed in the DO-214AB (SMC) surface-mount package, the SMCJ11A-13's copper tab on the cathode side carries the bulk of the thermal energy to the PCB copper plane. Cut Tape works for prototype or low-volume builds where the full reel commitment is not justified.

Frequently asked questions

What is the SMCJ11A-13's listed type and what does that mean for circuit protection?

The SMCJ11A-13 is a Zener-type TVS diode. Zener TVS devices clamp overvoltages by entering avalanche breakdown at a precise voltage — here 12.2 V minimum — and shunting the surge current to ground. The Zener construction gives a sharper breakdown knee than a standard diode, so the clamping voltage stays tighter across the pulse.

What package does the SMCJ11A-13 come in and how does it affect board layout?

The DO-214AB (SMC) surface-mount package. The package footprint is standard for the SMC family, so layout guides for other SMC TVS diodes apply directly.
