Using SM74611 as an OR-ing device
The SM74611 is Texas Instruments Smart Bypass Diode which externally connects as a regular 2-pin Schottky diode but offers a lesser forward voltage drop. It has a typical average forward voltage drop of 26 mV at 8 A of current. Taking the example of a 12 V, 8 A power supply, the 26 mV drop translates to a typical power dissipation of 208 mW. The SM74611 is also footprint and pin-compatible with conventional D2PAK Schottky diodes, making it a drop-in replacement in many applications. This device supports a maximum forward current of 15 A.
