Abstract
A semiconductor device is protected from electrical overstress (EOS) and electro-static discharge (ESD) events by a series protection circuit electrically coupled in series along the transmission line between a signal source and a load. The series protection circuit includes a first field-effect transistor (FET) electrically coupled in series between the signal source and load. A parallel protection circuit is electrically coupled between the transmission line and a ground node. The parallel protection circuit can include a transient-voltage-suppression (TVS) diode.
