1500 W peak pulse — what the 10/1000 µs rating means for your rail
The 1.5KE13CA R0G: The 11.1 V reverse standoff voltage means it sits across a 12 V rail without leakage concerns, and the 12.4 V minimum breakdown ensures the avalanche triggers before the protected circuitry sees damaging overvoltage.
Bidirectional single channel in a through-hole axial package
Single bidirectional channel — one device clamps both polarities, saving a diode pair on the board.
Sourcing and compliance
General-purpose application rating covers power-supply input protection, DC bus clamping, and signal-line transient suppression.
