PZU30B,115 Diodes - Zener - Single: Application Field and Working Principle

The PZU30B,115 Diodes - Zener - Single is a voltage-stabilizing semiconductor device that is able to maintain a constant, stable voltage across its terminals, in the presence of changing input voltages. It finds applications in a wide range of areas, including power conditioning, UPS, voltage regulation, and auto-protection circuits. This article will explain the application fields and working principle of the PZU30B,115.

Application Fields

The PZU30B,115 is used in a wide range of applications due to its ability to maintain a constant and stable voltage across its terminals. It is especially useful for applications that require accurate and consistent voltage in order to ensure proper system operation and performance. For example, in power conditioning and UPS applications, the PZU30B,115 can be used to reliably regulate the output voltage, regardless of the incoming source voltage. Similarly, the device can also be used to maintain stable voltages in automotive protection circuits. In addition, the PZU30B,115 is also used as a voltage reference in analog circuitry, as well as in voltage-controlled oscillators.

Working Principle

The PZU30B,115 Diodes - Zener - Single is an avalanche voltage-stabilizing device. It includes a Zener diode and an N-channel MOSFET connected in series. The Zener diode provides an efficiently-controlled voltage source, while the MOSFET acts as a voltage amplifying device.When the input voltage applied across the PZU30B,115 exceeds the breakdown voltage of the Zener diode, a large current is drawn through the device. This current causes an avalanche breakdown within the Zener diode, leading to a substantial increase in voltage across the terminals of the PZU30B,115. As the input voltage continues to rise, the current remains constant and the voltage continues to increase in a linear fashion.When the input voltage falls, the current through the PZU30B,115 decreases, allowing the device’s terminals to discharge and return to the breakdown voltage. In addition, the Zener diode acts as a voltage clamp, preventing the output voltage from rising above the breakdown voltage. Consequently, the PZU30B,115 is able to maintain a constant and stable output voltage, regardless of changes in the input voltage.

Conclusion

The PZU30B,115 Diodes - Zener - Single is a voltage-stabilizing device that is used in a wide range of applications. It is especially suited for power conditioning and voltage regulation, as well as for automotive protection circuits. The PZU30B,115 includes a Zener diode and an N-channel MOSFET, and works by drawing a large current through the device when the input voltage exceeds the breakdown voltage of the Zener diode, resulting in an increase in the output voltage. This allows the device to maintain a constant and stable output voltage, even when the input voltage changes.
