The SL24-B is an SMB RoHS (Restriction of Hazardous Substances) compliant Schottky Barrier Diode (SBD) manufactured by Formosa. It is used in a wide range of applications including AC/DC blocking, ESD protection, detection, and switching. The diode has a forward voltage of 0.68 V, a reverse-voltage of 10 V, and a current rating of 200 mA. It features an ultra-low capacitance and fast switching speeds that make it suitable for high-frequency circuit designs. The SBD is also RoHS compliant, meaning that it is free from hazardous materials, such as lead and mercury, making it safer for use in applications.
