The MMSZ4690-E3-18 diode is a Zener diode used to regulate an applied current or voltage with exceptional characteristics. This type of diode is particularly well suited for applications where reverse-biased breakdown is needed to maintain a critical rated forward current.

Typically, Zener diodes work on the principle of electric current passing through a reverse-biased p-n junction. When the voltage applied to the junction exceeds the Zener voltage (the voltage at which the current starts to reverse bias), a significant amount of electric current is allowed to pass through the junction. This breakdown current then creates a reverse-biased electric field which helps regulate the applied voltage over a wide range of voltage inputs.

The MMSZ4690-E3-18 is an 18 V Zener diode, meaning that the voltage applied to it must exceed 18 V before breakdown current can occur. This type of diode is relatively uncommon, as most applications require voltages of lower under normal conditions. However, the MMSZ4690-E3-18 is ideal for high-voltage applications such as power supplies, voltage regulators, overvoltage protection devices and other similar products.

The MMSZ4690-E3-18\'s key characteristics are a high rated standing power rating of 500 mW and a peak reverse power dissipation of 2 W. This ensures that regardless of the voltage applied, the diode will be able to withstand it without damaging the component or the circuit. Additionally, the MMSZ4690-E3-18 features an operating temperature range of -55°C to +150°C, meaning that the device can be used in a variety of applications, including both high and low ambient temperatures.

The MMSZ4690-E3-18 is a single Zener diode with exceptional characteristics and is ideal for high-voltage applications. It can withstand a wide range of voltages without damaging component or circuit, and its high standing power rating of 500 mW and peak reverse dissipation of 2 W make it suitable for applications requiring high reliability. Its operating temperature range of -55°C to +150°C means that the device can be used in a variety of different temperatures and environments.
