Diodes are an important part of electrical circuits. Diodes help to control and regulate the current flowing through a circuit by allowing current to flow in one direction only. Zener diodes are a type of diode that exhibit a different behavior than the regular diode. The Zener diode is designed to allow the current to flow in both directions but limits the maximum voltage allowed in the forward direction. This makes them suitable for use as voltage regulators and protection circuits. The BZX79-C75, 143 is a single Zener diode.

The diode has a maximum reverse voltage of 75 volts and it has a breakdown voltage of 74.5 volts at 25 degrees Celsius.

The BZX79-C75,143 is a single Zener diode that features very low leakage current as well as a low profile package. It has a very low power dissipation of 400mW and low capacitance. The diode has a maximum zener impedance of 93Ohms. The diode is also RoHS compliant, making it suitable for modern circuits.

Applications

The BZX79-C75,143 can be used in a variety of applications. The diode is commonly used in digital circuits to regulate the voltage within the circuit. The diode is also used to protect circuits from overvoltage and overcurrent. In addition, the diode can be used as a constant current source or a voltage reference. The low capacitance and low leak current make it ideal for high speed applications such as mobile phones and other digital devices.

Working Principle

The Zener diode works by allowing a limited current in the reverse direction. When a potential difference is applied across the diode, it causes conduction from the anode to the cathode. When a voltage across the diode reaches a certain level, the diode starts to conduct in the reverse direction, allowing current to flow in the opposite direction. This then prevents the voltage from increasing any further, thus regulating the voltage in the circuit.

When the Zener diode is used in a circuit, it is connected with the anode at a higher voltage than the cathode. This allows the current to flow in the reverse direction when the cathode reaches the breakdown voltage. The current then passes through the diode, allowing the voltage to be regulated at a certain level. The Zener diode also functions as a protection circuit, as it prevents the circuit from being overvoltaged due to excessive current.

Conclusion

The BZX79-C75,143 is a single Zener diode that can be used for a variety of applications. The diode is suitable for use in digital integrated circuits and it features low capacitance and leakage current. The diode can be used to regulate voltage in a circuit, as well as to provide overvoltage and overcurrent protection. The Zener diode works by allowing current to flow in the reverse direction when the voltage across the diode reaches a certain level, thus preventing the voltage from increasing any more.
