What is leakage current?

Leakage current flows unexpectedly in almost all circuits, even when the power is off. Current leakage is not limited to electronics, computers, or small signal circuits, and can be found in industrial equipment and three-phase wiring installations, too. Some current will always find a path to ground whether it''s through ground-conducting …

ESD protection for a low current device

Also, note the schottky has substantial leakage: just as it has a low forward drop at these currents, so too it will have a low drop at small reverse currents. Probably it takes just a fraction of a second for the supply to return to quiescent. And yeah, a TVS is a good combination with MOS polarity protection. Tim

At a lower voltage, say 1 V, the zener will already draw some current, what you may call ''leakage'' current, which is just jargon, but in any way, the zener will draw a non-zero current at voltages below the zener voltage. If you choose RS too large, the voltage over RL may never reach 3 V but may get stuck at a much lower voltage like 1 V.
