Application Field

The BZD27C8V2P-M3-18 is suitable for applications where it is required to regulate voltage by Zener breakdown in order to reduce fluctuations in the power rail. It is often used in portable electronic equipment, such as LCD screens, monitors and mobile phones because of its small size and high power handling capability. It can also be used in many other applications such as data transmission, power supplies and load switched systems.

Working Principle

The basic idea behind Zener breakdown is that when the voltage across the diode reaches a certain point, known as the Zener voltage (Vz), there is a rapid increase in the current flowing through the diode. This is because the diode has a built-in electric field which causes it to break down when the voltage exceeds a certain point. This breakdown creates a low-impedance path, allowing greater current flow.

The Zener voltage of the BZD27C8V2P-M3-18 is 8.0V. This means that when the voltage across the diode reaches this voltage, the diode conducts and the current increases exponentially. This increase in current is used to regulate the voltage, which can be used to provide a stable output power rail in applications such as data transmission, power supplies and load switched systems.

In addition to Zener breakdown, the BZD27C8V2P-M3-18 also has zener clamping. This is due to the relatively high breakdown voltage of 8V, meaning that the diode can also be used to clamp or limit voltages above its stated Zener voltage. This allows it to be used to protect ICs and other devices from overvoltage damage.

The BZD27C8V2P-M3-18 is a versatile Zener diode and can be used in many different applications. Its small size and high power handling capability make it suitable for portable, consumer and other applications. It can also be used in many other applications such as data transmission, power supplies, load switched systems and more. Thanks to its high breakdown voltage and zener clamping capabilities, it can also be used for protection.
