Working Principle

The BZG03C220-M3-18 is a single zener diode that is used for signals and protection applications. When the diode is forward biased, it will conduct current in the same way as any normal diode. When the voltage across the diode exceeds its breakdown voltage, the diode will switch from its off-state to its on-state and begin to conduct current. The amount of current that the diode can handle will depend on its wattage rating and the voltage of the circuit.

In reverse-biased current limiter applications, the diode is used to limit the current that can flow through the circuit. When the voltage across the diode exceeds the zener voltage, the diode will conduct current to prevent the voltage from exceeding the zener voltage. When used in this manner, the diode can be used to protect against excessive current, or it can be used to create a regulated voltage source.

In clipping circuits, the diode is used to clip the voltage from exceeding a certain voltage level. When the voltage exceeds the breakdown voltage of the diode, the diode will begin to conduct, limiting the voltage. When used in this way, the diode can be used to prevent spurious signals from propagating throughout a circuit.

Finally, the diode can be used in protecting against transient overvoltages. By connecting the diode in parallel with a voltage source, the diode will conduct current when the voltage across it exceeds the zener voltage. This will prevent the voltage from exceeding the zener voltage, preventing any damage to the circuit.

Conclusion

The BZG03C220-M3-18 is a single zener diode designed for the signal and protection applications. This diode can be used in a variety of applications, such as reverse-biased current limiting, signal diode, clipping circuits, and protection against transient overvoltages.
