Abstract
Apparatus and methods for electrostatic discharge (ESD) protection of radio frequency circuits are provided. In certain configurations, an integrated circuit includes a first pin, a second pin, a forward ESD protection circuit, and a reverse ESD protection circuit. The forward ESD protection circuit includes one or more P+/N-EPI diodes, one or more ESD protection devices, and one or more P-EPI/N+ diodes electrically connected in series between the first pin and the second pin. A first P+/N-EPI diode of the one or more P+/N-EPI diodes includes an anode electrically connected to the first pin. The reverse ESD protection circuit comprising one or more P+/N-EPI diodes, one or more ESD protection devices, and one or more P-EPI/N+ diodes electrically connected in series between the second pin and the first pin. A first P-EPI/N+ diode of the one or more P-EPI/N+ diodes includes a cathode electrically connected to the first pin.
