Diodes are electrical components that allow current to flow in one direction, but block current from flowing in the opposite direction. Zener diodes are a special type of diode used for voltage regulation and precision current control. A single Zener diode, such as the BZG05C75TR, can be used to provide a consistent voltage level or a specific current output. The application field and working principles of the BZG05C75TR will be explained in this article.

Application Field of BZG05C75TR

The BZG05C75TR is a single Zener diode, rated at 75V and 5W. It has low leakage current (1uA max @ 75V) and high power dissipation capability (5W). Due to its high power dissipation, high power Zener diode like the BZG05C75TR can be used in a variety of power and energy management applications. Common applications include:

• Clamping voltage on AC/DC converter input and output lines
• Limiting voltage of light dimmer circuits
• Over-voltage protection for servers and telecom equipment
• Voltage reference for AC/DC and DC/DC linear regulators
• Voltage control for electronic ballast

Working Principle of BZG05C75TR

The BZG05C75TR is a Zener diode; like all other diodes, the BZG05C75TR has two terminals: anode (A) and cathode (K). When the voltage applied across the diode terminals is higher than the specified Zener voltage, current will flow through the junction in reverse direction.

The electrical characteristics of the BZG05C75TR are listed in the datasheet. Its Zener voltage is specified at 75V, with a Zener current (I_Z) of 15mA and an operating power (P_Z) of 5W. The BZG05C75TR also has a maximum allowable non-repetitive peak reverse voltage (V_RM) of 100V, and a maximum allowable leakage current (I_LK) of 1uA at 75V.

The BZG05C75TR allows the voltage across the diode terminals to be clamped at a predetermined threshold, while limiting current flow through the diode. This makes it ideal for voltage regulation and voltage reference applications. When used as a voltage reference, the BZG05C75TR provides a precisely consistent output voltage as the current varies. This makes it possible for AC/DC and DC/DC linear regulators to provide stable voltage output.

Conclusion

The BZG05C75TR is a single Zener diode, rated at 75V and 5W. It is ideal for voltage regulation and voltage reference applications such as AC/DC and DC/DC linear regulators. The BZG05C75TR also offers low leakage current and high power dissipation, making it suitable for use in a variety of power and energy management applications.
