The SS22BF Schottky Barrier Diode (SBD) SMBF RoHS manufactured by Jingdao is a semiconductor that is used to prevent circuits from electrical overloading when current passes through it. It has a PN junction of two layers of opposite dopant type on each side. This diode is designed to block voltage flows in the reverse direction; thus, it can prevent circuit failure caused by high electric loads. This diode is RoHS compliant and is ideal for applications that require low forward voltage drops. Moreover, this SBD has a reverse leakage current as low as 2µA and highly efficient rectification performance.
