Single Zener Diodes

Single Zener Diodes are used for voltage regulation and stabilizing applications. They are ideal for low power devices, such as video cards, power supplies and lighting applications, where accuracy and reliability are desired. A single Zener diode can be used to regulate voltage in an entire circuit, and can be combined with other components to provide a protection feature to the circuit.

PZU5.6BL,315 Application Field

The PZU5.6BL,315 single Zener diode is designed to provide voltage regulation in 5 to 20V AC/DC applications. It has a breakdown voltage of 5.6V and can handle up to 0.5W of power in a surface mount package with clearly labeled pins for easy identification. It is also used for flyback and snubber applications. The diode is suitable for consumer and commercial applications, such as computers, cell phones, medical devices, home appliances, automotive and aerospace applications, and is UL approved.

Working Principle

The single Zener diode has a low forward voltage drop and its breakdown voltage is independent of temperature and manufacturing tolerance. It works by allowing a certain amount of current to flow through the P-N junction when the voltage across the diode is greater than the breakdown voltage. This flow of current then triggers a voltage drop equal to the breakdown voltage, allowing regulation of the voltage across the diode. If a higher level of current is supplied, the voltage across the diode will remain at its breakdown voltage, thus maintaining a stable state.

Conclusion

Single Zener Diodes are widely used in a variety of applications due to its ability to regulate voltage and provide stability. The PZU5.6BL,315 is an ideal choice for low power applications, with its surface mount package and its ability to handle up to 0.5W of power. Its breakdown voltage is independent of temperature and manufacturing tolerance and it works by allowing a certain amount of current to flow through the P-N junction when the voltage across the diode is greater than the breakdown voltage.
