Abstract: The present invention discloses parallel, series and hybrid ESD protection circuits. A preferred parallel ESD protection circuit comprises a plurality of ESD devices connected in parallel, with each comprising a resistor and an OTS component connected in series. A preferred series ESD protection circuit comprises a plurality of ESD devices connected in series, wherein the OTS components in all ESD devices are disposed on a same level. A preferred hybrid ESD protections circuit comprises ESD devices connected in parallel, as well as in series.
