Claim 10:
11. A device, comprising:
an integrated circuit;
an overvoltage protection circuit coupled to the integrated circuit, the overvoltage protection circuit including:
a first diode;
a second diode coupled in parallel with the first diode;
a node coupled to the first and second diodes;
a capacitor coupled to the node;
a resistor coupled to the node, the node being between the capacitor and the resistor;
an inductor coupled between the resistor and a first terminal of the integrated circuit, the resistor being coupled between the node and the inductor, the first and second diodes each 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.
