Abstract
New RC-Pi type ESD/EMI filters were fabricated using the integrated passive devices technology. Unique TVS diodes were employed to improve the electrostatic discharge (ESD) strength of the filters without sacrificing capacitance. The fabricated filter device has a cut off frequency of 270 MHz and the attenuation higher than −30 dB at >1 GHz. ESD testing results demonstrated the filter was capable withstand ±10 kV of IEC 61000-4-2 and handle positive TLP current up to 19 A. This evidence that excellent ESD performance can be found in the filter consist of the small TVS diode dimension of 50×50 μm 2 . The research results guide that employing TVS diodes are effective in the protection of data communication applications from very strong ESD shocks and noise disturbs.
