ZM4760A-GS18 is a single Zener diode, with a nominal breakdown voltage of 18V. It is usually used in applications where low voltage is important, such as controlling current flow in a circuit, voltage clamping, overvoltage protection, or providing precise reference voltage for analog circuits.

The main applications of the ZM4760A-GS18 are in the automotive, communication, industrial and consumer electronics. In automotive applications, it is often used to protect circuits from overvoltage or surge damage. In other electronics, it is used to precisely regulate power supply voltages, control current flow and provide a stable reference voltage. Zener diodes are also used in the protection of electro-sensitive devices such as smartphones, laptops, and tablets.

The ZM4760A-GS18 diode is constructed of a PN junction which acts as a barrier to the flow of current. The junction is formed by a heavily doped p-type region joined to a lightly doped n-type region. When the external voltage across the diode is less than the threshold voltage-Vz, the diode does not conduct and acts as an open circuit. When the applied voltage is greater than Vz, the diode exhibits a breakdown mechanism, allowing current flow through the junction.

This breakdown mechanism is referred to as a Zener breakdown, with the current flowing in the reverse direction, from the lightly doped n-type side to the heavily doped p-type side. This breakdown voltage-Vz-is determined by the dopant level used to manufacture the diode, and the ZM4760A-GS18 has a breakdown voltage of 18V. By controlling the dopant levels and applying an appropriate voltage across the diode, the current through the diode can be accurately regulated.

The ZM4760A-GS18 single Zener diode provides a precise and stable reference voltage, allowing analog circuits to operate at a precise voltage, even under varying load conditions. The device’s breakdown voltage can be precisely controlled by the dopant level and external resistor, allowing it to be used in a variety of systems in which accurate voltage control is important. Due to its low cost and high reliability, it is used widely in many electronics applications.
