GDZ24B-HG3-18 application field and working principle

Single zener diodes, such as the GDZ24B-HG3-18, are invaluable tools for facilitating the precise manipulation of voltages. As the name implies, the broad scope of applications can be divided into two distinct categories – regulating the voltages for different types of circuits, as well as protecting them from excessive voltages. In either case, the zener diode regulates the amount of current that passes through it by means of reverse bias. This means that the diode can be used to maintain a constant voltage even as the current flows through it in reverse.

Classic Application of Zener Diodes: Voltage Regulation

The classic application of a zener diode is its use in voltage regulation circuits. In this application, a fixed reference voltage is used to control the supply voltage of the circuit. This can be achieved by controlling the current through the zener diode. When the reference voltage exceeds the breakdown voltage of the diode, current will start to flow in reverse, thus regulating the voltage across the diode to the breakdown voltage. This technique is particularly useful when it comes to regulating sources of power, such as batteries or rectifiers.

Protection from Overvoltage: Clamping

Zener diodes can also be used to protect circuits from overvoltages. This is achieved by clamping the voltage across the diode to its breakdown voltage, thus preventing any further current from flowing. This type of application is especially useful when it comes to protecting sensitive components from voltage spikes or electrostatic discharges. Furthermore, it can be used to protect microprocessors or other logic circuits from any sudden increases or decreases in supply voltage.

Working Principle of GDZ24B-HG3-18

The GDZ24B-HG3-18 is a single zener diode that utilizes the breakdown voltage of the diode in order to regulate the voltage applied to the diode. The diode is composed of two distinct regions, the anode and the cathode. When a voltage is applied to the diode, electrons start to move from the cathode to the anode, creating a potential difference between the two regions. The current at which this potential difference is created is known as the breakdown voltage of the diode. By controlling the applied voltage, the current through the diode can be regulated to the breakdown voltage. This makes it possible to control the voltage applied to the diode, thus allowing for precise voltage regulation.

Conclusion

The GDZ24B-HG3-18 single zener diode is an incredibly versatile and powerful tool. Its primary application is in the realm of voltage regulation, where it can be used to create a constant voltage across the diode. It can also be used to protect circuits from spikes and other excessive voltages. This is accomplished by clamping the voltage to the breakdown voltage of the diode. By carefully controlling the amount of current through the diode, the GDZ24B-HG3-18 can be used to achieve precise and reliable voltage regulation.
