LS2405IDD23

LS2405IDD23 is a 24V, 5A very low forward voltage diode. It emulates a 5A very low forward voltage diode that is used in high current diode and diode-OR applications. The LS2405IDD23 integrates a 35mohm N-channel MOSFET to obtain higher efficiency and smaller board area to replace a schottky diode. LS2405IDD23 detects the forward voltage drop across the MOSFET to ensure the current transfer from one path to the other path smoothly, so it is easily used in the multiple power supplies OR applications that can effectively increase total system reliability. When the input supply fails or is shorted to ground, a fast circuitry can turn off the MOSFET immediately to reduce the reverse current. Applications include USB PD type C ports, muti-input power supply, telecom infrastructure, and automotive systems.
