Abstract
A semiconductor device includes a first diode having a first cathode and a first anode, wherein the first cathode is floating. The semiconductor device includes a second diode having a second cathode and a second anode, wherein the first anode is coupled to the second anode with the second cathode connected to a first supply voltage. The semiconductor device includes a third diode having a third cathode and a third anode, wherein the third cathode is connected to the first anode at an input/output pin, with the third anode connected to a second supply voltage. The second anode is coupled to a circuit that is powered by the first supply voltage and the second supply voltage. The first diode has a first size and the second diode has a second size, and the first size is substantially greater than the second size.
