TPD4S009 TVS Diode Arrays

HDMI, LVDS, SATA, and Ethernet applications all have one thing in common; they are all high-speed, differential signaling interfaces to the external world. To protect the ports for these interfaces, Texas Instruments has released the TPD4S009. This device offers four tightly matched ESD clamp circuits for dual differential lines. The monolithic silicon technology allows matching between the differential signal pairs, which is exceedingly important as data rates increase. Less than 0.05 pF differential capacitance matching ensures that the signal distortion due to added ESD clamp remains minimal. The 0.8-pF line capacitance is suitable for data rates in excess of 3 Gbps. The TPD4S009 offers uncompromised protection and complies with IEC61000-4-2 (Level 4) ESD. This device is offered in space-saving DRY (MicroQFN), DCK (SC-70), and DBV (SOT-23) packages.
