24V rail protection – where the breakdown window matters
The minimum breakdown voltage is 26.7V, meaning the device starts conducting just above the nominal rail — a tight window that protects 24V buses without nuisance triggering on normal ripple. Peak pulse power is 1500W (1.5kW) under the 10/1000µs waveform, with a clamping voltage of 43V at the peak pulse current of 34.9A. This combination suits it for secondary surge protection on DC power inputs, industrial control lines, and general-purpose circuit boards where a single bidirectional device replaces two unidirectional TVS diodes.
Junction temperature range and package fit
Product status is Active — no NRND or EOL flag, no last-time-buy pressure. This part is not single-sourced — the SMCJ family has broad distributor coverage, so dual-sourcing is straightforward if your volume warrants a second qualified line.
