1500 W peak pulse in a DO-214AB SMC body
The SMCJ26A-13-F: It clamps at 42.1 V maximum, with a 26 V reverse standoff and a breakdown voltage window starting at 28.9 V. Packaged in a DO-214AB (SMC) surface-mount body, it handles 35.6 A peak pulse current — enough to absorb a direct lightning surge or inductive load dump on a 24 V rail without cascading the failure upstream.
Clamping voltage and peak current — the real BOM-fit numbers
The 42.1 V clamp sets the voltage stress the downstream circuitry must survive. For a 24 V bus with a 30 % tolerance, the TVS triggers before the rail exceeds the downstream MOSFET or IC abs-max rating — typical for 40 V-rated DC-DC converters and 36 V-rated protection ICs. Peak pulse current of 35.6 A at the 10/1000 µs waveform means this part absorbs the energy of a single high-energy transient, not repetitive events — the 1500 W rating is a one-shot survival spec, not a continuous dissipation figure. The junction temperature limit of 150 °C is the hard ceiling for derating the pulse power.
Active production, sourced to order
It is available through independent distribution channels, quoted per RFQ with lot traceability and manufacturer warranty. Supplied on Tape & Reel (TR) with Cut Tape (CT) option for prototype builds. The DO-214AB SMC footprint is shared across the SMCJ26 base number family, so a single PCB layout serves the whole voltage range.
