600W surge clamp for 15V rails
With a peak pulse power rating of 600W (10/1000µs waveform) and a clamping voltage of 24.4V at 25.1A, it handles the kind of surge you get from inductive load dumps or lightning-coupled events on a general-purpose board. The 16.7V minimum breakdown voltage gives a clean trigger threshold before the silicon starts conducting hard.
DO-214AA footprint and temperature range
The junction rating means derating applies above 25°C; at 150°C the peak pulse power drops per the datasheet curve, but for most 85°C-max designs the full 600W is available.
For BOM planning that means no forced redesign window and no premium for end-of-life stock.
