The B5817W and B5819W are SOD-123 plastic-encapsulated Schottky barrier diodes. They feature high current capability, low forward voltage drop, and are housed in a small outline plastic package. These diodes are suitable for general purpose applications and offer a polarity band to denote the cathode end. They are Halogen free and RoHS compliant.
