Diodes, USB, Thunderbolt 3 interface, ultra-small

Diodes today introduced DESD3V3Z1BCSF-7, the most advanced data transmission line transient voltage suppressor (TVS) in the history of the industry. This product is designed for advanced system-on-chip with differential signaling lines up to 5 Ghz and provides excellent TVS / ESD protection for I / O ports, USB 3.1 / 3.2, Thunderbolt ™ 3, PCI Express® 3.0 / 4.0, HDMI 2.0a and DisplayPort ™ 1.4 and other high-speed interfaces indispensable components.

Modern SoCs are usually manufactured through advanced CMOS process nodes and are better able to withstand transient voltages and electrostatic discharges at I / O ports. The input channel capacitance of traditional TVS devices tends to be too high, easily degrading the high speed signal quality as the signal moves between the receiving system boundary and the SoC I / O port connector. The DESD3V3Z1BCSF-7 features ultra-low input channel capacitance (0.175pF typ.), Low dynamic impedance, low trigger / hold / clamp voltage, and advanced packaging using ultra-low capacitance using Diodes proprietary processes. Careful design results in very low insertion loss and meets the signal integrity requirements of high-speed interfaces such as USB 3.1 / 3.2 and Thunderbolt 3.

With the increasing popularity of advanced interfaces such as USB Type-C, the more necessary it is to protect the advanced SoC ports of Ghz class bandwidth. To ensure reliable operation of these SoC and USB Type-C ports, what is needed mostly now is the tiny TVS, which provides a high level of protection without compromising the integrity of high-speed signals. "Said Dr. Timothy Chen, Diodes' director of operations.

The industry-leading combination of clamp voltage (VCL = 4.5V typical for IPP = 3A), breakdown voltage (maximum VBR = 9V) and reverse isolation voltage (maximum VRWM = 3.3V) The peak pulse power (PPP) on the 8/20 μs short-circuit waveform is 25W.

The DESD3V3Z1BCSF-7 is available in an ultra-compact chip-scale X2-DSN0603-2 package measuring just 0.6mm x 0.3mm and a height of only 0.3mm.
