The PDZ8.2BZ is a single Zener diode that has wide applications and uses a unique working principle to operate. The diode operates under the principle of breakdown, or avalanche breakdown. This process occurs when a diode is biased with higher than its reverse breakdown voltage, causing a point of strong electric field within the diode, resulting in an avalanche of current carriers.

A Zener diode, otherwise known as a “breakdown diode”, can operate in either the forward biased mode or reverse biased mode, though it is primarily used in the reverse biased state. In this mode, the applied voltage can be monitored more easily and accurately, since the current is restricted to a very low level. When the maximum rated voltage is reached, the diode conducts and dissipates the applied voltage.

The PDZ8.2BZ is designed to be used with an anode voltage of 10V and a negative terminal voltage of 5V. The forward voltage drop is 0.8V, and the maximum achievable reverse leakage current is 1.2mA. It also has a maximum surge current rating of 3A, making it suitable for protecting sensitive equipment in high-voltage applications.

In high-voltage circuits, the PDZ8.2BZ can be used to generate a voltage reference, or as a voltage-limiting device. Additionally, it can be used in telecommunications systems, radio transmitters and receivers, and other high-frequency devices. The breakdown voltage can be adjusted using the temperature coefficient in order to regulate the output signal. The diode is also capable of withstanding extreme temperatures and can function without significant noise.

The PDZ8.2BZ is well-suited for use in applications that require a high-precision voltage reference or a voltage limiter, such as medical instruments, audio equipment, and industrial applications. Its ability to suppress noise and endure high temperatures make it a reliable component for applications where precision and operating temperature are a major concern. The fact that it operates with a low power consumption and relatively low reverse leakage current ensures that it is highly efficient and cost-effective.
