Tiny TVS for high-speed data interfaces

18 April 2018 Circuit & System Protection

Diodes Incorporated has announced its most advanced dataline transient voltage suppressor (TVS) ever, the DESD3V3Z1BCSF-7.

Designed to provide exceptional TVS/ESD protection to the high-speed input/output ports of advanced systems-on-chip (SoCs) featuring differential signal lines running at 5 GHz and beyond, the device is ideal for high-speed interfaces like USB 3.1/3.2, Thunderbolt 3, PCI Express 3.0/4.0, HDMI 2.0a and DisplayPort 1.4.

Modern SoCs are typically manufactured on advanced CMOS process nodes, which can make them more susceptible to transient voltages and electrostatic discharges appearing at the input/output ports. Due to the higher than desired input channel capacitance, 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.

The DESD3V3Z1BCSF-7 has been developed using Diodes’ advanced in-house processes to achieve ultra-low input channel capacitance (0,175 pF typical), low dynamic resistance, low trigger/holding/clamping voltages, and is assembled in a state-of-the-art package with ultra-low capacitance. Meticulous design results in exceptionally low insertion loss, meeting the signal integrity requirement of high-speed interface standards like USB 3.1/3.2 and Thunderbolt 3.

In addition to its ultra-low input capacitance, the DESD3V3Z1BCSF-7 offers exceptional ESD protection that meets IEC61000-4-2 requirements of up to ±8 kV air and contact. It features clamping voltage of 4,5 V typical for IPP = 3 A, breakdown voltage of 9 V maximum and reverse standoff voltage of 3,3 V maximum, while peak-pulse power dissipation (PPP) is 25 W over the short-circuit waveform of 8/20 μs.
