PDZ4.7B,135

The PDZ4.7B is a Zener diode, which belongs to the single diode type. It is commonly used in a variety of general purpose applications and switching power supplies. The PDZ4.7B can be used in systems that require a regulated voltage, such as voltage references, voltage dividers, and voltage drop circuits. It can also be used to protect circuits against reverse polarity and overvoltage.

The PDZ4.7B is a 4.7V voltage-regulating diode with a maximum power rating of 500mW. It is made of a low-leakage diffusion barrier and a silicon epitaxial layer, which allows it to have a very low forward voltage drop, making it suitable for regulating both AC and DC environments. Furthermore, it is capable of handling high peak power in pulsed operation and has a wide temperature range of -65°C to 175°C.

The working principle of the PDZ4.7B is based on the Zener Effect. As the applied voltage increases, a certain “knee” is reached, and the device starts to conduct and maintains a constant voltage drop on the output side. This is why the PDZ4.7B can be used as a voltage regulator. The device has a built-in voltage-limiting circuit, which limits the output voltage of the device to the intended voltage level and prevents excessive power dissipation.

The PDZ4.7B is used in a variety of different applications, including automotive electronics, industrial electronics, instrumentation, audio equipment, and telecommunications. It is also frequently used in the power supplies of computers and other home electronics, providing a stable power source for other components. Additionally, it is used in power limiting and protective circuits, where its ability to maintain a constant voltage drop is extremely useful.

The PDZ4.7B is a versatile device and is relatively easy to install, making it a great choice for a variety of general purpose applications. Its ability to maintain a constant voltage drop makes it a great choice for regulating voltage in systems that require it, and its built-in voltage-limiting circuit keeps the output voltage in check, helping to protect the system from excessive current. Its wide temperature range makes it suitable for use in both AC and DC environments, providing reliable operation no matter the conditions.
