PESD3USB3S/CX Application Field and Working Principle

The PESD3USB3S/CX is a type of TVS diode (Transient Voltage Suppression Diode). TVS diodes are semiconductor devices that are used to protect electronic circuits, such as a computer, against transient voltage surges and are often used in the protection of data lines. The PESD3USB3S/CX is specifically designed for USB 3.0 data lines. The PESD3USB3S/CX forms an integral part of the USB 3.0 system, as it is designed to protect the system against voltage surges from external sources. The PESD3USB3S/CX is a high-speed, low capacitance pick-off diode array, which can be used on USB 3.0 data lines for the suppression of transient voltages. The PESD3USB3S/CX has a very low series resistance, allowing for low input capacitance. The protection of data lines by the use of TVS diodes is essential, as it prevents damage to the components of a circuit, such as processors or memory chips, from transient voltage surges. In addition, some forms of interference can also be prevented by using TVS diodes - they are capable of blocking high-frequency noise before it reaches the circuitry.When voltage is applied to the PESD3USB3S/CX, the diode quickly conducts the surge current, clamping the transient voltage to a safe value. The PESD3USB3S/CX will conduct only until the transient voltage is blocked, and then it will immediately switch off, allowing the system to resume operation.The PESD3USB3S/CX is an advanced TVS diode, as it has been specifically designed to provide protection to USB cables. It features a low capacitance of less than 15pF/±0.2pF, allowing for a maximum voltage of 2.2kV. The PESD3USB3S/CX also features an ultra-low series resistance of 2Ω, which allows for low capacitance and low voltage, making it more efficient than other types of TVS diodes.The PESD3USB3S/CX is also capable of absorbing high-frequency noise, allowing for the clean transmission of data signals. This is due to its low capacitance, which reduces interference from external sources.In conclusion, the PESD3USB3S/CX is a highly effective protective device used to guard USB 3.0 data lines from transient spikes and noise. Its low-capacitance design allows for a maximum voltage of 2.2kV, while its low series resistance ensures the clean transmission of data signals.
