CZRER52C39 is a single Zener diode with a working voltage range of 3.4V to 150V. This diode is widely used in applications such as voltage regulation, voltage clamping, and overvoltage protection. It is also useful in applications where a low-voltage drop is required.

The device’s maximum power rating is 500mW and it can tolerate up to 3A of average current. The maximum breakdown voltage of this diode is 150V, while its maximum clamping voltage is 31V. The typical forward voltage drop of this device is 0.12V, while its reverse current is 5µA.

The CZRER52C39 diode is designed in a standard axial-leaded package, which provides a low inductance design for surface mount applications. It is RoHS compliant and is available in a wide range of sizes.

The primary application of CZRER52C39 is in overvoltage protection, where it is used to clamp transient voltages that otherwise might damage connected electronics. When various signals experience an overvoltage, the diode will consume the excess voltage, thus protecting the circuit and the connected devices.

The working principle of the CZRER52C39 diode is simple. In forward bias without an overvoltage condition, the diode behaves as a normal diode and has a forward voltage drop of about 0.12V. When an overvoltage is present, the diode will act as a clamp and allow current to flow in the reverse direction, up to the rated breakdown voltage of 150V. This prevents the voltage from damaging the connected circuit or devices.

The CZRER52C39 is also used in voltage regulator circuits. These circuits employ Zener diodes to maintain a steady, predetermined voltage, even in the face of changing current and voltage levels. The Zener diode is connected in parallel to the circuit and acts as a voltage clamp with a breakdown voltage set to the desired voltage. In these circumstances, the CZRER52C39 can provide a low voltage drop of 0.12V while still providing up to 3A of current, making it an ideal component for applications that require low dropout voltage regulation.

In conclusion, the CZRER52C39 diode is a single Zener diode with a working voltage range of 3.4V to 150V. It has a maximum power rating of 500mW and can tolerate up to 3A of current. Its primary application is in overvoltage protection and voltage regulator circuits. It is an ideal component for applications that require low dropout voltage regulation.
