Bidirectional Zener diodes have been around for decades, and with the ever-increasing capabilities of semiconductor technology, it is now possible to get much higher power ratings and more efficient designs. The PDZ3.3B,115 (hereafter referred to as the PDZ) is a single device that combines a Zener diode with a Schottky diode in one package. In this article we will discuss the application field and working principle of the PDZ.

The PDZ is designed to be used in a variety of circuit applications, from basic voltage regulation to more complex power management systems. It is commonly used in applications where a higher power dissipation is needed than what is achievable with a traditional Zener diode, or where the effective conduction voltage needs to be reduced. It is also used in AC voltage switching applications, such as in AC/DC power converters.

The PDZ is designed to operate in a bidirectional manner, allowing it to be employed for both voltage regulation and current limiting. The Schottky diode provides the rectifying action, while the Zener diode operates as a voltage regulator. This allows the device to be used in both voltage regulation and current limiting. The device also has a reverse recovery time of only 5 ns, which makes it suitable for high-frequency applications.

The PDZ is constructed of a dual dielectric, which provides superior reliability and heat dissipation. The device also has a planar structure, which ensures uniform current spreading and reduces stress on the device. Additionally, the device is available in a variety of package types, including SMD, TO-220, DPAK, and DIP packages.

The PDZ is a highly reliable device and is ideal for powering sensitive electronics and components. The device’s low forward voltage drop also makes it a suitable choice for applications where high efficiency is required. Additionally, its small package size and low cost make it a great choice for applications in space-constrained systems.

The PDZ operates on a simple principle that combines the conduction and regulation power of both the Schottky and Zener diodes. When the device is forward biased, the Schottky diode conducts current, while the Zener diode maintains the voltage regulation. When the device is reverse biased, the Zener diode will breakdown, regulating the voltage. This ensures that the device is able to achieve both conduction and regulation at the same time.

The PDZ is an extremely reliable, efficient, and cost effective device that can be used in a variety of applications. With its low cost, small package size, and high performance, it is sure to be a useful tool for any electronics designer. Whether for basic voltage regulation or for more complex power management systems, the PDZ can provide the right solution.
