The B2D20120HC1 is a Schottky Barrier Diode (SBD) manufactured by BASiC Semiconductor. It is a general purpose diode that is used to protect against overvoltage and short-circuit applications in a variety of electronic systems. This SBD is TO-247-3 compatible, which has three leads for connection to circuit boards. It operates between a breakdown voltage of 200V and a maximum reverse current of 25A and a peak reverse power dissipation of 100W. Furthermore, it is designed to reduce switching losses and the stored energy of an inductor. The B2D20120HC1 is RoHS compliant, meaning that it contains no hazardous substances, making it safe for use in the European market.
