Diodes has unveiled its latest dataline transient voltage suppressor (TVS) device in the data line protection product series. The DESD3V3Z1BCSF-7 protects the high-speed input/output ports of advanced systems-on-chips (SoCs) featuring differential signal line running at 5 GHz and beyond, from possible ESD hazards. Possible applications include smartphones, 4K/8K monitors, AR/VR equipment, PCs & computing peripherals, and Audio/Visual equipment.

The new TVS device is well-suited for protecting high-speed interfaces, such as USB 3.1/3.2 (up to 20 Gbps) and Thunderbolt 3 (up to 40 Gbps), PCI Express 3.0/4.0, HDMI 2.0a, and DisplayPort 1.4.

Traditional TVS devices can degrade high-speed signals as they travel between connectors at the boundary of the adopting system and the input/output ports of SoCs. This is due to their higher than desired input channel capacitance, Diodes said.

To overcome these challenges, the DESD3V3Z1BCSF-7 is said to achieve ultra-low input channel capacitance (0.175pF typical), low dynamic resistance, low trigger/holding/clamping voltages, and is assembled in a state-of-the-art package with ultra-low capacitance. An exceptionally low insertion loss meets the signal integrity requirement of high-speed interface standards like USB 3.1/3.2 and Thunderbolt 3.

“As advanced interfaces like USB Type-C become widely adopted, protecting the ports of advanced SoCs with multi-gigahertz bandwidth will become more imperative. To ensure reliable operation of these SoCs and the USB Type-C ports, the need for an incredibly low profile TVS able to provide a high level of protection without impacting the integrity of the high-speed signals is now paramount,” commented Dr. Timothy Chen, Division Director, Diodes Incorporated.

Another notable fact is an exceptional ESD protection according to IEC61000-4-2 requirements of up to +/-8kV air and contact.
