The B1D10120K with Schottky Barrier Diode (SBD) TO-220 RoHS is a semiconductor device manufactured by BASiC Semiconductor. It is a three-terminal device which uses a Schottky diode junction to allow current to flow in one direction only. Its features include low forward voltage drop, fast switching speed, and high breakdown voltage. The small size of the device makes its use in compact electronic circuits possible. The B1D10120K is RoHS compliant and is rated for a junction temperature of 150°C. It has a maximum peak repetitive reverse voltage of 100V, and a maximum average rectified forward current of 12A. The SBD is surface mountable, and comes in a TO-220 package, ideal for high current applications.
