What the 1500W rating means for your rail
The SMCJ14A-13-F: For a 14V nominal rail, the reverse standoff voltage (14V) sits below the line, so the diode stays out of the circuit during normal operation. When a transient exceeds the 15.6V minimum breakdown voltage, the device clamps at 23.2V maximum, shunting up to 64.7A of peak pulse current away from the protected load.
