An effect in semiconductors, the name of a diode that uses that effect and more generally any diode that has similar characteristics to a zener diode. Zener diodes have the unique characteristic of a reliable reverse bias breakdown voltage. Often used as simple voltage regulators or level shifters. Zener breakdown is a distinct effect common usage is any diode that has a fixed reverse breakdown are called "zeners" even if the mechanism is different.

It stops voltage spikes from travelling down that line the cathode is attached to. Just like a gate-source protection diode, once the voltage on L15 or L16 goes past Vzener, the zener clips it off. Basically stops you from overvoltaging whatever's on that line by the cathode. …

Do you even include it for an NMOS H-bridge? Because typically I've only ever seen them in NMOS/PMOS bridges, not full NMOS bridges. (Inductive load) The protection zeners would go here right?
