Diodes - Zener - Single

The BZV55C3V6 is a popular single power-rated Zener diode that is used for a variety of applications. The diode is capable of blocking up to 11.5V in the reverse direction and has a wattage rating of 5W. This allows it to be used for a range of different applications, from protecting integrated circuits to providing power-supply stability in communications systems.

BZV55C3V6 Applications

The BZV55C3V6 is most commonly used in applications requiring overvoltage protection, such as in power supplies, motor controllers, switching regulators, and communications systems. In these applications, the diode will limit the amount of voltage that can be applied to a sensitive component and prevent it from being damaged by an overvoltage situation. It can also be used as a voltage reference in voltage regulator circuits.

The power-rating of the BZV55C3V6 makes it suitable for use as a rectifier in high-power applications, such as in AC-DC converters, power control systems, and filter networks. It is also used as a clamping element in surge protection circuits, as the high power-rating allows it to dissipate large transient currents safely.

The BZV55C3V6 is also commonly used in AC circuits, such as in power factor correction applications. In these applications, it is used to create a high-impedance path for currents that would otherwise pass through the power supply, thus increasing the power factor of the system.

BZV55C3V6 Working Principle

The BZV55C3V6 is a Zener diode, which means it is designed to operate in reverse-bias mode, meaning that the current flows through the P-N junction in the opposite direction to conventional current flow.

When the diode is connected into a circuit, the voltage across the P-N junction will start to increase until it reaches the Zener breakdown voltage or Vz, which for the BZV55C3V6 is 3.6V. Once the voltage reaches the Zener voltage, the resistance of the diode suddenly drops to a very low value, allowing current to flow from the cathode to the anode.

This means that the diode will conduct in both forward and reverse bias, allowing it to act as an overvoltage protector or voltage reference. The BZV55C3V6 will limit the voltage applied to a device to 3.6V and prevent it from being damaged by higher voltages.

Conclusion

The BZV55C3V6 is a versatile power-rated Zener diode that can be used for various applications, including overvoltage protection, voltage reference, rectification, and AC power factor correction. The diode works by limiting the voltage that can be applied to a device to 3.6V and preventing it from being damaged by higher voltages.
