PLZ6V8A-HG3/H

Diodes - Zener - Single: PLZ6V8A-HG3/H Application Field and Working Principle

PLZ6V8A-HG3/H, also known as Zener Diodes, are used to construct a variety of circuits, and are particularly useful for regulating the voltage in electronics. This type of diode is actually a low-reverse leakage PN junction diode configured to work in the reverse direction, where the current enters from the anode and exits from the cathode. The current then flows through the diode, while the voltage at the anode remains constant.

Application Field

PLZ6V8A-HG3/H Zener Diodes are commonly used as voltage regulators and voltage stabilizers. They are well-suited for these applications because they can provide a constant and stable voltage even under varying input voltage conditions. This allows the electronics to be operated at a steady and reliable voltage level, thereby improving the reliability of the device.In addition, these diodes are widely used in oscillators, amplifiers, transformers, and other electronic components. They can also be used to construct rectifier bridges, which are used to identify high-voltage AC current. Furthermore, because of their low barrier breakdown voltage, they can be used in automotive and industrial control applications, where a low-reverse leakage limited input-to-output capacitance is required to ensure reliable operation.

Working Principle

When the current is reversed, the diode works in somewhat of a weird way: instead of behaving as an open circuit, it behaves as a short circuit. This means that when the applied voltage reaches a certain level (called the VZ or Zener Voltage) the diode becomes “forward biased”, allowing the current to flow through the diode, and thus the voltage drops to a value near the Zener Voltage. This phenomenon is often referred to as the Zener effect, and it is this characteristic that makes this diode so useful.The diode, when operating in the reverse bias, is quite similar to a normal diode in its inverse bias mode, and it operates on the same basic principle: the current flow, when reversed, will be limited according to the barrier voltage of the diode’s PN junction. In the Zener diode, however, the barrier voltage is lower than in a normal diode, and the current is limited accordingly.This makes the diode very useful in applications where the voltage needs to be regulated. The particular voltage at which the diode starts to conduct current in the reverse direction is known as the Zener voltage, and this can be easily adjusted by selecting the right type of diode and changing the value of the reverse bias voltage.
