Diodes - Zener - Single

The BZX84W-B2V4F is a single Zener diode that can be used to signal and protect circuits against voltage fluctuations. The device acts as a voltage regulator and typically limits the voltage to its breakdown voltage. The working principle of the device is simple: A Zener diode is usually a heavily doped diode, with its terminals connected in the opposite direction to the standard diode. It allows current to pass from the anode to the cathode as with a normal diode, but it also allows it to flow a “reverse” direction when the voltage exceeds a certain level – the “breakdown voltage”.

This allows the user to control the electrical current in the circuit by limiting the amount of voltage present in the circuit. When an electrical current passes through the BZX84W-B2V4F Zener diode, the voltage remains constant at the breakdown voltage. It makes the Zener diode useful for precise voltage regulation. It also allows it to act as a voltage dropping device, and creates a voltage-regulated path for current to pass through.

The main application for the BZX84W-B2V4F is to protect circuits from excessively high voltages. By using the diode in a circuit, the voltage can be prevented from exceeding its breakdown voltage. This is useful for preventing thermal runaway and other problems associated with too much voltage present in a circuit. It is also used to protect sensitive circuits from overvoltage, ensuring the safety of the circuit and any other connected components.

The breakdown voltage of the BZX84W-B2V4F is 5.1V, which is well suited for many applications. The device is also very small and has a low forward voltage drop, making it easy to integrate into a circuit. It is also fairly cheap, and available in both axial and surface mount packages.

The BZX84W-B2V4F is a very useful component, and is easy to integrate into circuit designs. It can be used to protect sensitive components and circuits from voltage spikes, and is an essential component for the reliable operation of any circuit. It is available in standard sizes, and is an affordable option for any circuit designer.
