PZU24BA,115

Diodes - Zener - Single

The PZU24BA,115 is a single zener diode, also referred to as a voltage regulation diode. It is a one-way current valve, meaning it restricts electrical current to flow through it in only one direction. The PZU24BA,115 is suitable for applications related to voltage regulation, voltage clipper and voltage stabilizers. These diodes are also often used to protect integrated circuits and transistors from overvoltage.

Application Field

The PZU24BA,115 has a wide range of applications and can be used in various electronic circuits. Common applications include voltage stabilizing systems, voltage clipper circuits, surge suppression, overvoltage protection, peak-to-peak detectors, and reverse current protection. On top of these, voltage regulation diode can also be used in RF amplifiers and voltage regulators.

Working Principle

The PZU24BA,115 operates on the principle of a zener breakdown. It contains an intrinsic semiconductor region between its two terminals where an electric field is intense. This intense electric field creates a zener voltage, also known as the Zener Voltage Vz, across the diode terminals. Under normal conditions, the Zener voltage Vz is below the peak inverse voltage of the diode.

When the external circuit’s voltage reaches the value of the Zener voltage Vz, a breakdown occurs and large amounts of current flow through the diode. This current causes a voltage drop and stabilizes the circuit’s output voltage. In other words, when the input voltage of the circuit exceeds the Zener voltage Vz, the diode conducts heavily and maintains a constant voltage at the diode’s output terminals by dissipating the extra voltage as thermal heat.

Package

The PZU24BA,115 diode comes in a small, through-hole package made of plastic. It measures 3.2mm in length and has a diameter of 2mm, allowing it to fit easily on a printed circuit board.
