uThe CRS01 is a Schottky Barrier Diode (SBD), which is a type of diode that uses a Schottky barrier to control current flow. The SBD CRS01 has a wide range of applications, such as high-frequency rectification, switching, voltage clamping, and is suitable for switching, protecting and regulating circuits in automotive, communications and safety equipment. It has SOD-123FL package, meaning that the package is small and flat, with a total of three leads. The SBD CRS01 is RoHS (Restriction of Hazardous Substances) compliant, meaning it contains no lead or other toxic materials. Furthermore, it is manufactured by Shikuesu, a Japanese company that produces reliable semiconductor products.
