TVS - Diodes

TVS - Diodes are simple electronic components used in a variety of applications. They assist in limiting the voltage that passes through a circuit and can be used for both over-voltage and over-current protection.The VBUS051CD-HD1-G-08 is a low-capacitance, diode array Silicon TVS Diode suitable for ESD, EFT, lightning, and pulse current protection.

Application Field

The VBUS051CD-HD1-G-08 is a high-speed diode array designed to protect two differential data line pairs. The device is often used to protect Ethernet data lines, USB interfacing, Computer Peripherals, PCMCIA and other telecom and datacom portal applications.This device is designed to protect two differential data line pairs, and provide very fast response times with controlled capacitance for better signal integrity. The VBUS051CD-HD1-G-08 comes in a space-saving VQFN-6L package with a lead-mite design for better board-level grounding.

Working Principle

The TVS diode works on the principle of reverse breakdown of a semiconductor diode. When voltage is applied across a diode in the reverse direction, power is dissipated in the form of heat before the device breaks down. During this process, the voltage across the diode decreases gradually until it reaches a certain value called the reverse breakdown voltage.When this occurs, current passes through the diode in the reverse direction, and the device is said to be in the breakdown mode. This peak value of the current is defined as the peak pulse current rating, or Ipp.The VBUS051CD-HD1-G-08 includes two low-capacitance TVS diodes connected in series for each input line. This diode combination is optimized for minimal capacitance while clamping against ESD events. The two series-connected TVS diodes help absorb large amounts of ESD energy and also help balance the operating voltage, also referred to as clamping ratio.

Conclusion

The VBUS051CD-HD1-G-08 is an excellent choice for applications that require low capacitance across differential data line pairs. It offers excellent ESD, EFT, lightning, and pulse current protection, with a low clamping ratio and low capacitance. The device comes in a space-saving VQFN-6L package and with a lead-mite design for better board-level grounding.
