The SMAJ5.0CAQ-13-F: The 5V reverse standoff (working voltage) means the diode draws negligible leakage below 5V — it stays invisible on the rail until a transient pushes the line above 6.4V, the minimum breakdown voltage. Power line protection is not supported — this is a signal- or low-power-rail TVS, not a mains-side suppressor.
