Working Principle

The MMSZ5237C-G3-18 works on the fundamentals of PN junction diode. It contains two semiconductor regions that are separated by a thin layer of PN material, which acts as a barrier. When an electric current (DC) is applied to this junction, electrons move from the N-type material to the P-type material. This process is known as forward biasing, wherein electrons carry the flow of current in one particular direction and the diode behaves like a resistor.

When the voltage reaches breakdown voltage, known as the Zener voltage, the diode begins to operate in reverse bias. Electrons then flow from the P-type material to the N-type material, resulting in a large current flow. The Zener effect occurs precisely because of this current flow, thus stabilizing the output voltage. In this manner, the MMSZ5237C-G3-18 acts as a voltage regulator and provides a stable, reliable voltage output.
