PZU3.9B,115 Diodes - Zener - Single

Zener Diodes are a type of diode commonly used for voltage regulation. The PZU3.9B,115 is a single Zener diode with a breakdown voltage of 3.9 volts and an operating temperature range from - 55°C to 125°C. It is designed to protect circuits from overvoltage damage and provide stable and accurate regulation.

Application Fields

The PZU3.9B,115 Zener diode is primarily used in the protection of electronic circuits and components that are sensitive to overvoltage. This could include voltage regulation circuits such as voltage regulators or voltage limiters, signal and power supplies, and high-voltage circuits. It can also be used in a variety of other applications, including in test and measurement, communications, industrial control, and automotive electronics.

Working Principle

Zener Diodes work by providing a low-resistance path for current to flow in one direction when the voltage across the diode reaches the specified breakdown voltage, or Zener voltage. The device is operated in the reverse-bias region with no current flowing until the voltage across it reaches the breakdown voltage. At this point, the diode begins to conduct in the reverse direction, allowing current to flow. This current is limited by the maximum reverse voltage rating of the diode, and the diode will dissipate the excess energy and keep the voltage to the specified breakdown voltage.

The Zener diode offers an easy and efficient way of providing voltage regulation by allowing current to flow through the diode in either direction without any damage to the device. It has the added advantage of being a low-cost and simple solution compared to traditional linear voltage regulation solutions.

Conclusion

The PZU3.9B,115 is a single Zener diode that is designed to provide a stable and accurate source of voltage regulation in a variety of applications. This type of diode is ideal for protecting sensitive circuits from overvoltage damage and for providing low-cost and simple solutions for linear voltage regulation.
