The GDZ2V4B-G3-08 is an single Zener diode manufactured by IXYS Corporation, a leader in the supply of power semiconductor components. It is a high-performance diode composed of glass-passivated, junction silicon. It is typically used in AC-DC application designs such as voltage regulating circuits, voltage absorbing circuits, and voltage clamping applications. It is also used in AC-DC conversion circuits, DC-DC conversion circuits, voltage holding circuits, and diode bridge waveform circuits.

The GDZ2V4B-G3-08 is a high-voltage device capable of sustaining an operating voltage of up to 200V. It also features a zener voltage of 4.8V and a nominal zener impedance of 3.5 Ω. The GDZ2V4B-G3-08 is available in a compact, TO-92 package, making it suitable for space-constrained applications. It also features a forward-voltage drop of ≤ 0.2V, ensuring a low power dissipation and making it ideal for power efficient applications.

Application Field of GDZ2V4B-G3-08

The GDZ2V4B-G3-08 is ideal for various AC/DC power applications. Its high-quality construction makes it perfect for power supplies, DC-DC converters, inverters, and voltage regulator circuits. The low forward voltage drop and high-sustaining voltage of the GDZ2V4B-G3-08 make it suitable for applications requiring long-term stability. It also features a high surge capability and can be used for voltage clamping applications.

Working Principle of GDZ2V4B-G3-08

The GDZ2V4B-G3-08 is a single zener diode, which means that it is composed of a single p-n junction. It utilizes the zener effect, which occurs when a reverse-biased diode is subjected to a high reverse-bias voltage. As the voltage increases, a point is reached at which the diode becomes partially conducting, allowing a portion of the current to flow in the reverse direction. The point at which this occurs is the Zener breakdown voltage, in this case 4.8V.

Using this principle, the GDZ2V4B-G3-08 can be used to create a voltage buffer in AC/DC power designs. When the voltage exceeds the breakdown voltage, a portion of the current passing through the diode will be diverted, forming a stable voltage source. This can be used to provide a steady source of power in AC/DC and DC/DC conversion circuits.

The GDZ2V4B-G3-08 is also capable of sustaining high reverse-bias voltage and is therefore suitable for voltage clamping applications. By using a reverse-biased diode and a resistor, a voltagediverting circuit can be created to regulate the amount of current flow through the circuit. The GDZ2V4B-G3-08 can be used to limit the maximum voltage in an AC/DC power supply and thus provide protection from over-voltage conditions.

Conclusion

The GDZ2V4B-G3-08 is a high-performance, single-zener diode manufactured by IXYS Corporation. Its low forward-voltage drop and high breakdown voltage make it ideal for powering AC/DC designs such as power supplies, DC-DC converters, voltage regulator circuits, and voltage clamping applications. In addition, its space-saving TO-92 package makes it suitable for tight spaces.
