With so many electrical components on the market today, it is important to know the correct device for the application. MMBZ4707-E3-18 is a zener diode that can be classified as a single, low-power 3 watt device. In this article, we will discuss the application field and the working principle of MMBZ4707-E3-18.

A Zener diode, also known as a voltage-regulator diode, is a device that is primarily used to provide a specific and stable voltage in electrical circuits. Zener diodes are a type of diode that allows current to flow in the forward direction just like a normal diode, but also allows it to flow in the reverse direction when the voltage is above their breakdown voltage. The MMBZ4707-E3-18 is a 3 watt zener diode that has a zener voltage of 18 volts, with a typical reverse current of 3.0 mA and a maximum power dissipation of 2.4 watts. The diode makes use of a Silicon substrate in its construction.

The application field of the MMBZ4707-E3-18 mainly involves the protection and regulation of other components from excessive voltage or current. When the zener diode senses a voltage or current that is above its rated voltage or current, it switches on and provides a regulated voltage to the circuit. This prevents other components from over-voltage or over-current damage. The MMBZ4707-E3-18 can also be used to provide a constant voltage output in power supplies, and in automobile and motor starters.

When it comes to the working principle of the MMBZ4707-E3-18, the diode allows current to flow in both directions. However, it will only pass the current to the circuit when the voltage is higher than its breakdown voltage. This means that when there is a sudden surge in voltage, the diode will be activated and allow the current to pass to the circuit, thus providing protection from over-voltage and over-current. The zener diode has a structured design that works in the reverse bias direction when the voltage is below the diode\'s breakdown voltage. When the voltage is above the breakdown voltage, the diode conducts current in the reverse direction.

Apart from its protection and voltage regulation functions, the MMBZ4707-E3-18 can also serve as a voltage reference. Voltages are usually applied directly to the diode, which is then used to adjust the other circuit elements to certain values. This makes it extremely useful in power supply applications and TC utilities.

In conclusion, the MMBZ4707-E3-18 is a 3 watt zener diode that can be used for the voltage regulation and protection of other components from adverse voltage and current. It can also serve as a voltage reference in power supply applications and TC utilities. Its application field and working principle are discussed in this article.
