Working Principle

The SZNZ3F75VT1G works on the principle of reverse-biased breakdown. When a reverse voltage is applied, the electric field in the p-n junction region increases due to the back bias. As this electric field reaches a certain strength, electrons can break free from their atoms and, together with holes, form a current across the junction, allowing current to flow in the reverse direction.

This breakdown process is known as Avalanche Breakdown and occurs when reverse voltage exceeds the zener voltage. The zener diode then operates in its zener breakdown region and limits the voltage, preventing further increases in voltage.

The SZNZ3F75VT1G is a versatile component that can be used for a wide range of applications. Thanks to its robust performance and wide variety of applications, it is a popular choice for electronics designers.
