1、New Product Launch
Recently, JY Electronics has introduced the TS0321TB-Fx, a surge protection device specifically designed for high-speed signal lines. The TS0321TB-Fx utilizes JY’s proprietary ultra-low capacitance technology and advanced packaging technology to provide surge protection for ultra-high-speed signal lines.
2、Wide Applications of TS0321TB-Fx
The TS0321TB-Fx is highly suitable for surge protection of high-speed signal lines such as USB 2.0/3.0/3.1, USB Type-C, LVDS, HDMI, and more. It can be widely applied to desktop computers, laptops, gaming consoles, high-definition TVs, monitors, wearable devices, TWS (True Wireless Stereo), IoT modules, and more. The product is now available for bulk shipment.
3、Highlights of TS0321TB-Fx
①Ultra-Small Package: The TS0321TB-Fx features a DFN1006-2L ultra-small package (1.0 mm × 0.6 mm), which is compact in size and maximizes PCB space savings.
②Low Capacitance and High Surge IPP: With an ultra-low capacitance of 0.62 pF, it also offers a Surge IPP of 14A (tested under an 8/20μs waveform), providing strong surge protection while ensuring the integrity of high-speed signals.
③Deep Snapback Leading-Edge Technology: The device employs JY’s unique deep snapback leading-edge patent technology, with a clamping voltage of 6V@IPP=14A. Compared to non-snapback and shallow snapback devices, JY Electronics’ deep snapback devices offer lower clamping voltage protection for circuits.

4、USB 2.0 Application Case and Recommended Selection

The TS0321TB-Fx chip perfectly meets the protection requirements for USB 2.0 devices, providing strong surge protection while ensuring the integrity of high-speed signals. It also utilizes JY’s unique deep snapback leading-edge patent technology, offering lower clamping voltage protection for circuits.
