The MMSZ4696-E3-18 is a single Zener diode designed to protect components from over-voltage. It works by utilizing the volt-ampere characteristic properties of a diode to limit the voltage across a device under protection. The device is designed specifically for applications that need to have low power dissipation, such as voltage regulation in power supply design.

The MMSZ4696-E3-18 is capable of dissipating power as low as 0.2 W and operate from -55oC to +150oC temperature range. The device has a Zener voltage range from 4.3 V to 13.0 V with a maximum Zener impedance of 10 mΩ at a junction temperature of 25oC. It has a typical leakage current of 5 μA and maximum leakage current of 100 μA. The device has a maximum power dissipation of 500 mW, a working temperature range from -55oC to +150oC, and a maximum operating current of 200 mA.

In operation, the MMSZ4696-E3-18 works by allowing current to pass through it in only one direction, when the voltage supplied to the device is below the specified threshold. When the applied voltage exceeds the Zener voltage, the current across the diode increases, which allows the device to limit the voltage to a pre-determined value. This voltage regulation is especially useful in power supply designs as it prevents over-voltage and other related conditions that can damage components.

In addition to being used as a voltage regulator in power supply designs, the MMSZ4696-E3-18 can also be used in a variety of other applications, such as reverse polarity protection, ESD protection, and over-voltage protection. As the device is capable of withstanding high power and temperature, it is also commonly used in battery chargers and AC adapters.

The MMSZ4696-E3-18 is a reliable and efficient component that can be used to protect sensitive electrical components from over-voltage. Thanks to its low power dissipation and high temperature tolerance, it is well suited for use in a variety of applications. With its wide range of capabilities, the MMSZ4696-E3-18 can be an invaluable component for protecting components from over-voltage conditions.
