The K24 is a 500uA@40V 40V Single 550mV@2A 2A SOD-123FL Schottky Barrier Diode (SBD) ROHS manufactured by Doeshare. This diode is a semiconductor device and is designed to allow current to flow in only one direction, blocking the flow in the other direction. With a forward voltage drop as low as 550mV, and a maximum current rating of 2A, the K24 is designed to be used in a variety of high-current, low-voltage power applications. The SBD is also designed to offer enhanced performance over the standard diode, including higher efficiency, faster switching times, lower power dissipation, and improved current leakage. The ROHS rating on this part ensures that it is compliant with the industry standards for reducing hazardous materials.
