Most designers consider slowness in diodes to be an imperfection or a limitation. Why not take a more positive view of the situation? After all, a zener or an avalanche diode is no more than a diode ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
