The GDZ20B-G3-18 diode is a single zener diode with high stability and breakdown voltage. It is mainly used for voltage regulation, surge current protection, electric current clamping, electric current steering and circuit voltage division. Generally, diodes are classified by their electrical characteristics, including the breakdown voltage, reverse leakage current and maximum allowable voltage. The GDZ20B-G3-18 diode belongs to a single zener diode, which can provide a stable voltage over a wide range of current. It is suitable for applications such as voltage stabilization, surge current limiting and power supply design.

The GDZ20B-G3-18 diode has a breakdown voltage of 18 volts, which is the maximum voltage applied to the diode in a forward bias state. When the voltage exceeds the breakdown voltage, the diode is broken and the voltage is stabilized. This allows a constant output voltage, which is useful for regulating voltages in the power supply. The reverse leakage current of the diode is relatively low, and it does not require much power. In addition, it can handle high power currents efficiently, making it suitable for applications such as power supplies, voltage dividers and clamping.

The working principle of the GDZ20B-G3-18 diode is simple. In the forward bias state, the voltage across the diode is increased, and when the voltage exceeds the breakdown voltage, the diode breaks down and a large amount of current flows through the diode. As the breakdown voltage is constant, the voltage across the diode stabilizes, allowing a constant voltage output. In the reverse bias state, the diode acts as an open circuit and no current flows. When current flows through the diode, it acts as a resistor and the current is limited by the resistance.

In conclusion, the GDZ20B-G3-18 diode is a single zener diode with a constant breakdown voltage and low reverse leakage current. It is mainly used for voltage regulation, surge current protection, current clamping, current steering and voltage division. The working principle of the diode is that in the forward bias state, the diode breaks down and a constant voltage output is obtained. In the reverse bias state, the diode acts as an open circuit and no current flows.
