Vishay Intertechnology has introduced six new surface-mount Schottky barrier rectifiers housed in a low-profile package which will help designers to save board space.

Schottky barrier rectifiers are often supplied in larger SMA and SOD123W packages. The new SS1FL3, SS2FL3, SS1FL4, SS2FL4, SS1FH10 and SS2FH10 devices are in an SMF package measuring just 2.8mm x 1.8mm x 1mm. This is 46% lower than an SMA package, and 23% lighter. It cuts the board footprint almost in half.

The SS1FL parts are also notable for their low forward voltage drops, which reduce power losses and enable power-system designers to improve efficiency. The rectifiers’ flat-lead package also offers thermal resistance of 21°C/W from junction to lead, compared to the conventional SMA J-lead package’s thermal resistance of 28°C/W.
