Texas Instruments SM74611 Smart Bypass Diode

Texas Instruments SM74611 Smart Bypass Diode is used in photovoltaic applications and provides an alternate path for string current when parts of the panel are shaded during normal operation. TI SM74611 Smart Bypass Diode has a lower forward voltage drop than P-N junction and Schottky diodes. It has a typical average forward voltage drop of 26mV at 8A of current. This translates into typical power dissipation of 208mW, which is significantly lower than the 3.2W of conventional Schottky diodes. SM74611 is also footprint and pin compatible with conventional D2PAK Schottky diodes, making it a drop-in replacement in many applications.
