The SS34L with 40V Single 3A 0.55V@3A SOD-123FL Schottky Barrier Diode (SBD) ROHS manufactured by Hottech is a semiconductor diode that is used to reduce electrical losses and prevent reverse polarity, or reverse current flow, in circuits. It is a surface-mount type device, with a SOD-123FL package, and is compliant with the RoHS directive. The SS34L has a 40-volt maximum forward voltage drop, a 3-amp continuous forward current rating, and a 0.55-volt maximum reverse leakage current. It is ideal for power-supply-voltage-level conversion, rectifying, and switching applications.
