The SS12 SBD SMA RoHS (made by LGE) is a type of Schottky Barrier Diode, which is a semiconductor device characterized by providing very low forward voltage drop and fast switching speed. This device is designed to be used in a wide range of applications including power supplies, low-frequency and high-frequency switching, rectifying, and signal-processing appliications. It has an ultra-fast turn-on speed and low forward voltage drop, making it ideal for noise suppression and high-frequency-driver switching. The SBD is made from Silicon and its surface is coated with a special alloy, known as the Schottky barrier layer to suppress leakage current. Furthermore, this device is RoHS-compliant, meaning that it does not contain any materials that are hazardous to the environment. It is packaged in the SMA size and there are multiple pins for electrical connection.
