1.1 ESD and Surge Protection Using LANTSPD-C8 & WPE3V3D3ULA

This solution is applicable for transmission rates of 10Mbps/100Mbps/1000Mbps/2.5Gbps/5Gbps. The secondary stage uses a small-package SOD-323 low-capacitance ESD suppressor for protection, offering ESD protection up to 30KV, effectively preventing interference caused by electrostatic discharge. The primary stage uses a semiconductor discharge tube combined with an RC circuit, providing effective common-mode surge protection up to 8KV (10/700μs).

2.1 ESD and Surge Protection Using WPT5V0D1MF & WPE05VN92ULA

USB 2.0 typically employs line-to-ground ESD and surge protection technology, with a maximum signal rate of 480Mbit/s. A SOD-123FL package TVS is used between VCC and GND, providing ESD protection up to 30KV. For the signal lines, a small-package DFN1006-3L low-capacitance ESD suppressor is selected for protection, offering ESD protection up to 20KV.

3.1 ESD and Surge Protection Using WPE5V0N16AT1L1 & CLAMP0521PSCR1

Compared to previous versions, the USB 3.2 interface features faster transmission speeds, with a data transfer rate of up to 10Gbps. It adds SSRX+/SSRX-/SSTX+/SSTX- differential signal pairs compared to USB 2.0, requiring enhanced ESD and surge protection capabilities. The signal lines are protected using a chip-scale CSP0603-2L ultra-low capacitance ESD suppressor, which occupies minimal PCB area and provides ESD protection up to 20KV. Vbus is protected using a small-package DFN1610 ESD suppressor, offering ESD protection up to 25KV.

4.1 ESD and Surge Protection Using WPE5V0N16AT1L1 & CLAMP0521PSCR1

The widely used HDMI 2.1 version currently supports a maximum transmission rate of up to 48Gbps. Given the high-speed and multi-channel signal transmission of the HDMI interface, it is essential to prevent ESD transient pulses during product usage from interfering with normal HDMI communication or potentially damaging the HDMI interface control chip. The signal lines are protected using a chip-scale CSP0603-2L low-capacitance ESD suppressor, which occupies minimal PCB area and offers ESD protection up to 20KV. The 5V Power line is protected using a small-package DFN1610 ESD suppressor, providing ESD protection up to 25KV.
