Zener diodes are a type of diode that allows current to flow in the forward direction similar to a normal diode, but will also allow it to flow in the reverse direction when above a certain reverse voltage. The PLZ20A-G3/H is a single zener diode. It is used in many devices, including computers, medical and laboratory equipment, electric motors, and many other high-power and high-voltage applications. This article will discuss the application field and working principle of the PLZ20A-G3/H zener diode.

One of the most common application fields of the PLZ20A-G3/H zener diode is in the control of circuit voltages. When the maximum allowable voltage is exceeded, the diode’s reverse conduction will limit the voltage to a set level, protecting the circuit from damage. This voltage regulation can occur in a wide range of input voltages and currents, making the PLZ20A-G3/H suitable for many applications. It is also used for transient voltage spike protection, as its reverse voltage conduction will limit the voltage to a set level.

The PLZ20A-G3/H diode works by using a depletion region that is connected to a p-type region and an n-type region. When the reverse voltage is applied, the depletion layer expands and blocks current flow in the reverse direction, acting as an insulator. When the voltage is increased to the zener voltage breakdown point, the depletion layer collapses and allows a small current to flow. This zener voltage breakdown point can be adjusted to the desired set level.

Another application field for the PLZ20A-G3/H diode is in voltage clamping. Voltage clamping involves placing a diode between the input and output of a circuit. When a voltage spike occurs, the diode’s reverse conduction capability limits the voltage to the breakdown voltage of the diode. This protects the circuit from the overvoltage and allows it to continue operation at the normal output voltage.

The PLZ20A-G3/H zener diode also has application fields in signal processing and power supply regulation. It can be used in signal processing by connecting it to the signal line and using it to limit signals to certain voltage levels. This is useful in data communication systems, as it prevents signals from becoming too large and damaging the control circuitry. It can also be used to regulate power supplies by keeping them from exceeding the maximum allowable voltage.

In summary, the PLZ20A-G3/H is a single Zener diode which is used in a wide range of applications, including circuit protection, signal processing, and power supply regulation. It works by using a depletion region that is connected to a p-type region and an n-type region, and is able to limit voltsages to the breakdown point of the diode. This makes the PLZ20A-G3/H suitable for a variety of applications and is a popular choice for many electronics manufacturers.
