400 W peak pulse, 26 V standoff — the SMAJ26A-13-F in the DO-214AC footprint
It clamps transients at 42.1 V maximum, passing up to 9.5 A peak pulse current before the junction absorbs the event. The 26 V standoff means this TVS sits across a 24 V nominal rail — it stays transparent below 28.9 V (minimum breakdown) and only conducts when a surge pushes the line above that threshold. The 400 W rating at the 10/1000 µs pulse gives the energy capacity for industrial transient events like inductive load dumps or lightning-coupled surges on field wiring. Packaged in the standard DO-214AC (SMA) surface-mount footprint, it reflows on the same profile as common diodes and small-signal transistors — no special handling beyond the usual ESD precautions for a TVS junction.
For a 24 V rail TVS in the DO-214AC package, the SMAJ26A-13-F is a drop-in fit wherever the SMAJ26A family is called out. The -13-F suffix indicates the Tape & Reel packaging variant for automated pick-and-place.
Temperature range and deployment context
The wide TJ max of 150°C gives margin for self-heating during repetitive surge events. No power line protection rating — this is a signal-rail or low-power bus TVS, not intended for direct AC mains clamping. It protects DC rails up to 26 V nominal, such as 24 V sensor supplies, PLC I/O lines, or CAN bus power feeds.
