High-speed TVS

27 April 2011 Circuit & System Protection

STMicroelectronics has addressed ESD protection for equipment such as DisplayPort monitors and PCs by introducing a transient voltage suppressor (TVS) allowing increased high-definition (HD) picture quality, thanks to its very low capacitance.

The high signal speeds of DisplayPort, as well as similar external connections such as HDMI, USB3.0 and eSATA, call for improved protection devices that prevent electrostatic pulses from damaging the system’s circuits, as users add or remove cables. These are connected to each pin of the external connector to absorb or divert the ESD pulse energy, but must add the lowest possible capacitance on the signal line to avoid degrading picture quality.

ST’s new ESDAXLC6-1MY2 places a loading of 0,35 pF maximum on the signal line. This low capacitance provides a signal bandwidth of 6 to 7 GHz, which allows the 2,7 Gbps data streams of a DisplayPort interface to pass through without distortion. By using the same footprint and pin arrangement as older devices of higher capacitance, the new TVS provides a direct upgrade or second source for any existing product. It occupies just 0,6 mm² of printed circuit board space, and only a single device is required per signal line. The protection provided meets IEC 61000-4-2, allowing equipment to withstand an ESD event up to ±8 kV in direct contact with the signal conductor.
