The 1.5KE18A R0G: Reverse standoff voltage is 15.3 V typ — the line sits below this during normal operation without leakage. Breakdown occurs at a minimum of 17.1 V, and clamping peaks at 25.5 V, defining the protection voltage window for the downstream circuitry. The device is rated for continuous junction temperatures from -55 °C to 175 °C, covering industrial and automotive under-hood ambient ranges without derating the pulse power at the high end.
