The 1N4733A is 5.1V, 1W, Diode.

A voltage regulator diode, also known as a Zener diode, is a type of diode that is specifically designed to maintain a constant voltage across its terminals when it is operated in the reverse-biased direction.

Unlike regular diodes that are primarily used for rectification purposes, Zener diodes are designed to operate in the breakdown region of their reverse-biased characteristics. This means that they are designed to conduct current in the reverse direction once a certain voltage, known as the “Zener voltage” or “avalanche voltage,” is reached.

The primary function of a voltage regulator diode is to stabilize or regulate the voltage across a circuit or a specific component. When a Zener diode is properly connected in a circuit, it can limit or “clamp” the voltage at a specific level, preventing it from exceeding that level. This makes Zener diodes useful for voltage regulation and protection against voltage spikes or surges.
