Classification: CPC H | IPC H

Claim 10:
11. A device, comprising:
a substrate of a first conductivity type;
a drift layer of the first conductivity type, the drift layer having a first surface;
a first implanted region of a second conductivity type extending into the drift layer from the first surface, the first implanted region having a first dimension in a first direction;
a second implanted region of the second conductivity type extending into the drift layer from the first surface, the second implanted region having a second dimension in the first direction, the second implanted region being spaced from the first implanted region by a third dimension in the first direction, the third dimension being less than the second dimension, the third dimension being less than the first dimension;
a first terminal on the first surface of the drift layer, the first terminal being on the first and second implanted regions, the first terminal having a fourth dimension in the first direction, the fourth dimension being greater than a sum of the first, second, and third dimensions;
a first Schottky diode between the first terminal and the drift layer between the first and second implanted regions;
a first junction barrier diode between the first implanted region and the first terminal; and
a second junction barrier diode between the second implanted region and the first terminal.
