The NZX4V3D,133 is a single Zener diode that is used in various applications. It is a three-terminal device with two anode terminals and one cathode terminal. In the two-terminal application, the anode is connected to one terminal and the cathode is connected to the other terminal.The NZX4V3D,133 is commonly used to regulate the voltage across two components in an electrical circuit.

Application Field

The NZX4V3D,133 is used in a wide range of applications. It can be used to regulate the voltage across two components in an electrical circuit, including in power supplies, and to regulate the current through a resistor in a voltage divider circuit. The Zener diode can also be used to protect other components from overvoltage, to create a reference voltage for op-amp circuits, to regulate the gain of a transistor, and to provide positive feedback for a transistor that is used as an oscillator.

The NZX4V3D,133 is also used in various signal conditioning applications. It can be used to limit the peak-to-peak voltage of a signal, to reduce the power of a signal, or to provide impedance matching for different signal frequencies. In addition, the Zener diode can be used in analog signal conditioning applications, such as active dropout compensation, gain peaking, amplitude regulation, and signal limiting.

Working Principle

The NZX4V3D,133 operates by having an applied voltage, either direct current (DC) or alternating current (AC), exceeding the diode’s reverse breakdown voltage. When the applied voltage reaches the level of the breakdown voltage, the Zener diode begins to conduct current. The current then passes through the diode, with the amount of current dependent on the Zener breakdown voltage.

It is important to note that the Zener breakdown voltage is not fixed and can vary depending on the temperature and other factors. The breakdown voltage is typically specified at a particular temperature, usually 25-degrees Celsius, and at a particular current. Additionally, the breakdown voltage can have a wide range of values, typically between 4 and 5 volts.

The NZX4V3D,133 is designed to have a low inherent capacitance, which is beneficial for applications requiring high-frequency signal conditioning. Additionally, the Zener diode exhibits temperature stability, meaning that the breakdown voltage will not vary significantly with temperature. The Zener diode also has a low forward voltage drop, which helps reduce losses associated with signal conditioning.

Conclusion

The NZX4V3D,133 is a single Zener diode that is used in a variety of applications including voltage regulation, protection of other components, impedance matching, and analog signal conditioning. It has a breakdown voltage that is typically between 4 and 5 volts and exhibits low inherent capacitance and temperature stability. The low forward voltage drop helps reduce signal conditioning losses.
