The MMBZ4686-E3-08 is a single, small surface-mount package, Expitaxial Zener diode commonly used in important industrial applications. It is specifically designed to provide a stable Zener voltage over its operating temperature range. The device is specifically designed for use in DC and AC applications, where low noise and low distortion are important considerations.

The MMBZ4686-E3-08 device is ideal for use in applications such as DC/DC converters, voltage regulators and power switching circuits, as well as in industries where noise or distortion levels must be kept to a minimum. With its built-in protection from over-voltage, over-current and temperature related events, the MMBZ4686-E3-08 ensures a higher level of reliability for your system.

The MMBZ4686-E3-08 diode is designed with a PN junction which operates as a Variable Voltage Limiter for voltage greater than the Zener Voltage. This ensures that the voltage across the device will not exceed the rated limit even in cases of transient conditions. The device has a rated reverse standoff voltage of 9.1V and a maximum leakage current of 10µA when the operating temperature is as low as -55°C. The junction capacitance (at 1.0MHz and reverse bias of 7V) is 250pF.

The MMBZ4686-E3-08 is also designed with a maximum power dissipation of 500mW allowing it to operate under power levels up to 9V and 25mA. The device is rated with a Maximum Zener Voltage of 7.5V and a load stability of 5% at 25mA. This diode can also be used in AC applications. The Maximum Reverse Current (Iz) is specified at about 50mA at a reverse voltage of 6V.

The MMBZ4686-E3-08\'s working principle is based around the PN junction which is designed to work as a voltage limiter, ensuring that any voltage above the rated limit will be safely limited by the device. The device is designed to operate in reverse biased condition, where the breakdown voltage is the zener voltage. When the diode is connected in reverse biased condition, a maximum electric field is created across the junction for a given voltage and leakage current starts to flow through the diode. As soon as the reverse voltage reaches the breakdown voltage, the electric field is intensified and the current increases drastically. This effect is known as the Zener Breakdown.

The MMBZ4686-E3-08 is a highly versatile diode which can be used in a wide variety of industrial applications. This includes switching power supplies, voltage regulators, and AC/DC applications with low noise and low distortion. The device\'s ability to limit voltage and handle high temperatures makes it especially suited for use in rugged industrial systems where reliability is essential. The device also has excellent thermal stability, making it an ideal choice for temperature-sensitive applications.

Overall, the MMBZ4686-E3-08 is an excellent choice for a variety of industrial applications requiring reliable voltage and temperature stability. The diode\'s PN junction is designed to serve as a voltage limiter for overvoltages, the device handles high temperatures, and its low leakage current of 10µA makes it a great choice for low noise and distortion levels. With a maximum power dissipation of 500mW, high load stability and rated maximum reverse current of 50mA, the MMBZ4686-E3-08 is a perfect choice for industrial applications.
