Diodes - Zener - Single

A Zener diode is a type of semiconductor device that can be used to protect electrical systems from high-voltage surges. A Zener diode, also known as a voltage regulator, is a two-terminal, solid-state device designed with a built-in PN junction. It works by keeping the voltage across its electrodes at a constant level, regardless of any changes of the current or voltage applied. The VDZT2R2.2B is a Zener diode specially designed for use in the protection of electronic circuits.

Application Field

The VDZT2R2.2B Zener diode is designed for use in a wide range of industrial, automotive and consumer applications. It can be used to provide voltage regulation, voltage stabilization, and transient protection in a variety of situations. Common uses include motor control and power systems, inverters, and other power applications where voltage stability is essential.

The unique design of the VDZT2R2.2B allows it to be used in a wide range of temperature conditions, from -65°C to 125°C. It is also designed to withstand harsh environmental conditions, such as vibration and shock. The device is certified in accordance with the standards of the RoHS (Restriction of Hazardous Substances).

Working Principle

The VDZT2R2.2B works by using its integrated PN junction. It is designed to only allow current to flow from the Cathode to the Anode in one direction. Once the voltage across it’s PN junction reaches a certain value, called its Zener voltage, the diode\'s internal resistance drops sharply. This allows the current to flow in both directions, without any overvoltage spikes damaging the electronic components.

The VDZT2R2.2B is designed to have break-down voltage of 2.2V +/- 5%. It has a high-temperature operating temperature of -65°C to 125°C and maximum operating power of 500mW. The maximum peak current is limited to 1A, while the maximum reverse leakage current is 5µA. The diode is available in the standard SOT-323 SMD package.

Conclusion

The VDZT2R2.2B is a Zener diode designed for use in a wide range of automotive, industrial and consumer applications. It is designed with a built-in PN junction and is able to provide voltage regulation and transient protection. The diode has a designed break-down voltage of 2.2V +/- 5%, a high temperature operating temperature of -65°C to 125°C, a maximum operating power of 500mW and a maximum peak current of 1A.
