Zener diodes are widely used in many circuits in the electrical industry, specifically the PLZ22C-G3/H Zener diode. This particular diode model is a single directional device that has designed to regulate a voltage either higher or lower than its specified operating conditions. This article will discuss the application field of the PLZ22C-G3/H diode and its working principle.

Application Field

The PLZ22C-G3/H Zener diode is commonly used in semiconductor applications. It is an ideal device for all sorts of voltage regulation, including for integrated circuits, which are the basis for most modern electronics and digital devices. Additionally, this type of diode is used for protection from voltage spikes, noise immunity and suppression of line transients. It can also be used to provide predetermined breakdown voltages for other applications such as SSR (solid state relays), and opto-couplers. This diode also offers “cold start” protection over the range of 8.8 up to 52VDC.

Working Principle

The PLZ22C-G3/H Zener diode is designed with a particular anode-cathode junction which will start flow and conduct current once the reverse voltage exceeds a predetermined breakdown level. Furthermore, it uses an efficient and reliable avalanche breakdown mechanism which allows current to pass through the diode once the breakdown voltage is reached.

During normal operation, the diode acts as a normal non-conducting diode, meaning the current entering the anode is insufficient for the device to act in the conduction state. In other words, the voltage across the junction has to be greater than the rated voltage of the device in order to activate the current and allow the device to act as a conducting diode.

The voltage regulation of a Zener diode is usually set by the manufacturer, and is usually lower than a corresponding power diode. This makes The PLZ22C-G3/H effective in creating constant current and voltage stabilization in circuits. It also has fast switching and good performance when responding to temperature changes.

Conclusion

The PLZ22C-G3/H single direction Zener diode is a powerful and reliable device for many applications in the electrical industry. In conclusion, it can be used for voltage regulation and protection from voltage spikes, line transients and noise immunity. Additionally, its unique design makes it a great choice for use in all sorts of applications, such as SSR and opto-couplers.
