CD0603-Z4V7 Discrete Semiconductor Products

Diodes - Zener - Single

The CD0603-Z4V7 diode is an example of a Zener diode and it is classified in the category of single a diodes. A Zener diode is a type of diode which, when reversed biased, allows an electric current to flow in the reverse direction.

Application Field

The CD0603-Z4V7 Zener diode has a variety of uses. It can be used for power regulating applications and for providing protection against reverse energy surges. This type of diode is mainly used for protecting circuits in consumer electronics like TVs, radios, and computers. It can also be used for high-voltage switching operations.

Working Principle

When the voltage is applied in the forward direction, the diode acts as a regular diode, meaning it only allows current to flow in the forward direction. When the voltage is applied in the reverse direction, the diode allows a small amount of current to flow in the reverse direction. The current is determined by the zener voltage of the particular diode. In the case of the CD0603-Z4V7 , the zener voltage is -4.7 volts.

When the voltage is applied in the reverse direction, a voltage drop occurs and produces a small reverse current. This reverse current will be constant no matter how large the applied voltage grows. This is known as Zener breakdown because it occurs when the voltage is greater than the Zener voltage in the diode. So, for the CD0603-Z4V7 , the reverse current will remain constant when the applied voltage is greater than the -4.7 voltage.

In addition to its voltage regulating ability, the CD0603-Z4V7 also has some other useful abilities. It has a fast response to changes in current, can handle higher reverse voltages, has a very low forward voltage drop, and can also reduce the power needed to operate the circuit. These characteristics make them very useful for many different applications.

Conclusion

The CD0603-Z4V7 is an example of a single Zener diode. It is suitable for use in regulating power and protecting from reverse energy surges. It is also useful for high-voltage switching operations. It has a very low forward voltage drop and its reverse current is kept constant with an applied voltage greater than its Zener voltage of -4.7 volts. The CD0603-Z4V7 is therefore an excellent choice for any circuit that needs precise voltage regulation.
