Replacement for diode solutionsEpcos extended its CeraDiode CDS4 series with a 3pF type that has the same solder pad dimensions (2.5-by-0.8mm) as a TVS diode in an SOD 323 package; hence, the company said, the new type CDS4C16GTH can be used as a drop-in replacement for diode solutions so that customers can avoid expensive and time-consuming redesign of circuit boards.

Due to the low capacitance of 3pF, signal distortion is largely avoided. Contemporary semiconductor solutions, on the other hand, which cannot drop below the 5pF threshold, cannot satisfy demands for higher transmission rates, said Epcos.

The company also offers a standard type (CDS4C12GTA) rated at 68pF with the same footprint. This variant is used for general ESD protection and as an EMC filter. Both types have a response time of <0.5ns. Further advantages include low leakage currents and no degradation at temperatures up to 85C.
