PD3Z284C22-7

Diodes are among the most common electronic components. These devices are used to convert electrical current from one polarity to the other, aiding in the operation of many electronics. One type of diode, the Zener diode, is a specialized device that allows reverse current flow at a specific voltage value. The PD3Z284C22-7 is one Zener diode, designed to regulate current in specific applications.

PD3Z284C22-7 Application Field

The most common application for the PD3Z284C22-7 is voltage regulation in aircraft systems. It is rated for a maximum of 300 volts with a maximum current of 100 mA, both of which fall below the maximum limits for aviation systems. The diode\'s low thermal resistance and its ability to effectively regulate current make it ideal for aircraft power conditioning applications.

The PD3Z284C22-7 is also used in industrial electronics, specifically in the manufacture of machine tools and automated production systems. These applications require steady, reliable currents to be maintained and the diode delivers this needed consistency effectively. With a maximum power rating of 5 milliwatts and a wide range of operating temperatures, the PD3Z284C22-7 is well-suited for industrial automation needs. Additionally, the diode has a very long life, with a nominal life of one billion cycles and a maximum cycle life of five billion cycles.

PD3Z284C22-7 Working Principle

The PD3Z284C22-7 works by allowing current to pass in either direction, but limiting current flow when it exceeds the diode\'s rated voltage. When the current is below the rated voltage, both directions of current flow unrestricted through the diode. However, when the current exceeds the rated voltage, the diode works to limit the current, essentially regulating the flow of current. This regulation helps maintain constant voltage levels in the circuit, preventing damage from over-voltage.

The PD3Z284C22-7 is rated for both AC and DC power sources and can effectively regulate current in either application. When both polarity of current is present, the diode helps limit the maximum power and maintains a steady voltage level. This helps electronic devices function properly without disruption or damage.

Conclusion

The PD3Z284C22-7 is a specialized type of Zener diode designed to effectively regulate current levels. While it is often used in aircraft and industrial applications, it can also be used in general power conditioning circuits. This diode offers reliable performance with a long cycle life, making it suitable for many applications.
