Diodes - Zener - Single: PZU4.7B, 115

PZU4.7B, 115 is a single Zener diode, commonly used to stabilize or regulate voltage supply in electric circuits. It employs a diode whose junction is reverse biased, allowing the current to flow in one direction only.

Types

PZU4.7B, 115 is a type of Glass-passivated Zener diode, which means it features a hermetically sealed glass body that prevents contamination. The body is also resistant to humidity, which ensures long life and improved reliability. In addition, there is a reverse breakdown voltage of 4.7 volts with a tolerance of 5%.

Uses

PZU4.7B, 115 has a variety of uses in a wide range of electronic applications, such as voltage regulation, voltage clamping, and voltage reference. They are commonly used for in circuits that require accurate control of current and voltage to ensure proper operation. PZU4.7B, 115 is especially useful for automotive and aerospace applications where accuracy and reliability are of utmost importance.

Characteristics and features

PZU4.7B, 115 features a capability to dissipate power of 0.5 watts and a maximum operating temperature of 150°C. When used in series, the zener diode is able to block high voltages that may occur due to load or component failure. In addition, it has a low impedance and can operate over a wide range of temperatures, making it suitable for use in high-frequency and high-speed circuits.

Working Principle

The working principle of PZU4.7B, 115 is based on the principle of reverse operation of a diode. When a forward bias is applied on the diode, it will act as a closed switch and does not allow any current to pass through. On the other hand, in case of a reverse bias, the diode will become forward biased and current will start to flow through it.

In the case of PZU4.7B, 115, the diode is designed to provide a stable voltage output even in the case of an input voltage that is above 4.7 volts. As such, when a voltage of more than 4.7 volts is applied to the circuit, the diode will cause the voltage to stabilize at 4.7 volts, thus providing a useful regulation capability.

Safety Features

In addition to its voltage-stabilizing features, PZU4.7B, 115 is equipped with several safety features. For example, the diode can operate in temperatures up to 150°C, before the diode becomes damaged or unstable. Furthermore, the device is overload-protected to ensure the stability of its output voltage.

Conclusion

PZU4.7B, 115 is an invaluable component for voltage regulation and voltage reference in a range of electronic applications. Its glass-passivated body helps protect the device from contaminants, while its temperature and overload protection helps ensure its reliability. Furthermore, its low impedance and wide temperature range make it suitable for high-speed and high-frequency circuits.
