DDZ9716S-7 Discrete Semiconductor Products

Diodes - Zener - Single are single Zener diodes assembled in one package, which are widely used in the electronics industry. Among them DDZ9716S-7 is one type of them. It is a silicon epitaxial planar zener diode with a zener voltage range of 6.8V to 7.2V. It has a power dissipation of 200mW and a peak reverse power dissipation of 400mW as well. DDZ9716S-7 is a convenient alternative to assembling individual diodes or manually cutting and mounting diodes into a board.

Application Field

DDZ9716S-7 is a common zener diode, which are widely used in electronic devices in the following application field:

Power supply circuit

Zener diodes can be used in power supply circuits to protect against transients and voltage surges. When a voltage higher than the normal operating voltage is applied to the circuit, the Zener diode will conduct and not allow the voltage to exceed the diode\'s breakdown voltage, limiting the voltage to the safe level and protecting circuit components from damage. DDZ9716S-7 can protect the circuit with its wide range of breakdown voltage.

Signal conditioning circuit

Signal conditioning circuit also uses Zener diodes. Zener diodes are used to create a reference voltage so that the output voltage follows the reference voltage regardless of the input voltage changes. This is especially useful when the output voltage is independent of the input voltage. In this case, the DDZ9716S-7 guarantees that the output voltage is within the zener voltage range of 6.8V to 7.2V without being affected by the input voltage.

Clamps and voltage dividers

Zener diodes can also be used in clamps and voltage dividers. When a voltage higher than the breakdown voltage is applied to a circuit, the Zener diode will conduct, limiting the voltage to the breakdown voltage. DDZ9716S-7 can also be used in voltage dividers, depending on the voltage range required. By choosing a suitable breakdown voltage, they can be used to divide voltage as well.

Working Principle

The working principle of Zener diodes is based on the Zener effect. Zener diodes are heavily doped with p-type and n-type semiconductor materials, creating a heavily doped junction. When an external voltage is applied, the junction bends the electron energy bands, creating a narrow energy gap, and allowing the electrons to cross and flow freely in reverse. When the voltage reaches the breakdown voltage, the current flowing through the device increases sharply.

DDZ9716S-7 is particular to conventional Zener diodes in that it has a wide voltage range. This ensures that the breakdown voltage is within the expected voltage range before use, and that the current flowing through the device does not exceed the specified level at the same time, so that the device remains within the safe operating voltage range.

Conclusion

In summary, DDZ9716S-7 is a common zener diode and it is widely used in the electronic industry. Its application fields include power supply circuit, signal conditioning circuit, clamps, and voltage dividers. Its working principle is based on the Zener effect and it provides a wide voltage range to ensure that the breakdown voltage stays within the safe voltage range.
