What the 3 kW peak pulse power means for your 12 V rail
For a 12 V nominal system, the 10 V reverse standoff voltage sits below the rail, so it stays out of the way during normal operation. When a transient hits, breakdown starts at 11.4 V and clamping is guaranteed at 17 V maximum with 176 A of peak pulse current. That clamping voltage is what the downstream electronics see — keep it under the absolute maximum of any powered IC on that rail.
Automotive grade and temperature range — where this part lives
If your design targets an automotive ECU, ADAS sensor module, or any 12 V system that sees load dump and ISO 7637 pulses, this is the grade you need.
