The MBR1040DS is a Schottky Barrier Diode (SBD) with a TO-252 RoHS package, manufactured by Jingdao. The MBR1040DS is a 40V, 1A Surface Mount Rectifier Diode with ultra low forward voltage drop. It features a high level of efficiency and performance, is designed specifically for the switch mode power supply (SMPS) market, and is perfect for a wide range of applications. This diode is RoHS compliant, and is capable of handling up to 1A at 40V without significant losses due to forward voltage drop. Its low forward voltage drop helps minimize the power consumption and cost of the system.
