WS3A008065A is a Schottky Barrier Diode (SBD) TO-220 RoHS manufactured by China Electronics Technology Company (CETC). It is an integrated circuit device that functions as a diode, allowing current to flow in one direction and blocking it from flowing in the other. Its fast switching speed, low forward voltage, and temperature stability make it useful in a wide range of power electronics applications. It is RoHS-compliant, meaning it does not contain any hazardous substances, and is rated to be operational at -55°C up to 150°C. The maximum reverse leakage current is 1uA at 100V.
