A PZU18B2,115 Zener diode is a single diode designed to maintain a constant voltage across its layer junction under varying currents. It has a wide variety of applications, ranging from power supplies to radio frequency (RF) signal processing. In this article, we\'ll go over the application field and working principle of the PZU18B2,115 Zener diode in detail.

Application of PZU18B2,115 Zener Diode

The PZU18B2,115 Zener diode is typically used in voltage regulator circuits, voltage reference circuits, and overvoltage protection circuits. It can also be used in audio amplifier, oscilloscopes and other signal generator circuits. Other applications include DC-DC converters and power converters, and it can also be used as a voltage reference in precision applications. It can also be used to regulate the voltage in radio frequency (RF) signal processing circuits.

The PZU18B2,115 Zener diode is designed to handle up to 1.5A of continuous current with a maximum voltage of 18V. It has a low reverse leakage current and very low leakage current at zero bias, meaning it uses very little power in standby mode. This makes it ideal for power-efficient, low-power designs.

Working Principle of PZU18B2,115 Zener Diode

The PZU18B2,115 Zener diode works on a simple principle. When the voltage across the device\'s zener junction is below its threshold voltage, the diode remains off and no current will flow through it. Once the voltage across the zener junction exceeds the rated voltage of the device, current will start to flow, and the voltage across the diode\'s layer junction will remain constant at the rated voltage of the diode. This allows the device to regulate the voltage, keeping it within a set range even when current is applied to it.

The zener voltage of the PZU18B2,115 Zener diode is 18V with a 5mA minimum current. It also features a temperature coefficient of 2.8mV/°C which ensures a stable voltage over temperature variations. The capacitance of the diode is very low just 2pF, meaning it exhibits almost no capacitive effects when used in RF applications.

Conclusion

The PZU18B2,115 Zener diode is a single diode designed to regulate and maintain a constant voltage across its layer junction. It has a wide variety of applications, ranging from power supplies to radio frequency (RF) signal processing. It is designed to handle up to 1.5A of continuous current with a maximum voltage of 18V, and it has a low reverse leakage current and a very low leakage current at zero bias. This makes it ideal for both high-power and power-efficient designs. Its working principle is simple - when the voltage across the zener junction is below its threshold voltage, it remains off. If the voltage exceeds the diode\'s threshold voltage, current will start to flow and it will regulate the voltage across its layer junction to the rated voltage of the diode.
