The CZRQR52C3V9-HF is a single Zener diode with a 3.9 volts breakdown voltage axial package. It is a high current, low voltage Zener, made from high reliability silicon chips. It has a peak forward current of up to 50 amps and a maximum inverse operating current of 4uA. The CZRQR52C3V9-HF is a very popular device that is commonly used in voltage regulation, voltage protection, and wave clamping applications.

A Zener diode is a general purpose semiconductor device that is designed to regulate voltage by allowing a certain amount of current to flow in the reverse direction when a certain voltage is applied to the diode. The breakdown voltage of the diode The CZRQR52C3V9-HF is 3.9 volts, which means that the diode begins to conduct reverse current when the diode is exposed to a voltage of 3.9 volts or more. This breakdown voltage determines the operating voltage of the Zener diode.

Application

Due to its high current capability, the CZRQR52C3V9-HF Zener diode is well suited for voltage regulation, voltage protection, and wave clamping applications. It is particularly useful for voltage regular static and dynamic applications, where it can be used to protect sensitive electronic components from high voltage or overvoltage transients. It is also suitable for wave clamping applications such as suppressing ESD (electrostatic discharge) transients.

The CZRQR52C3V9-HF can be used in a variety of voltage regulation and voltage protection applications, such as circuit protection and crowbar protection. In circuit protection applications, the Zener diode can be used to protect components from high voltage transients, and in crowbar protection applications, the diode can be used to limit current spikes in circuits. It can also be used for edge detection applications, where it can detect voltage transitions on the input signal and convert it into a square wave.

Working Principle

The working principle of the CZRQR52C3V9-HF Zener diode is based on the PN-junction. When the Zener diode is exposed to a voltage of 3.9 volts, a certain amount of current begins to flow in the reverse direction. This current is limited by the diode’s zener impedance, which prevents further voltage increases and protects the electronic components in the circuit. This current is called reverse leakage current and it is the basis for the Zener diode’s voltage regulating capabilities.

The CZRQR52C3V9-HF Zener diode is capable of withstanding high temperature and current surges due to its high reliability silicon chips and its operating temperature range of -55°C to 125°C. It is also very resistant to aging due to its low leakage current and its RoHS compliance. It is an ideal choice for applications where overvoltage protection and voltage regulation are needed.
