Claim 6:
7. A device, comprising:
an overvoltage protection circuit that includes:
a first diode;
a second diode coupled in parallel with the first diode, each of the first and second diodes including:
an intrinsic region;
a doped region in the intrinsic region;
a ring-shaped region around the doped region, the ring-shaped region extending into the intrinsic region further than the doped region; and
an insulator on the intrinsic region, on the ring-shaped region, and partially overlapping the doped region such that a portion of the doped region is left uncovered by the insulator;

a resistor coupled to a data signal and coupled to the first and second diodes;
a connector having a first terminal and a second terminal, the first terminal coupled to the resistor and to the first and second diodes; and
an inductor coupled to the second terminal.
