Rectifier offer 0.63Vf at If of 12 Amps with 120 V voltage limiting

Diodes Incorporated has expanded its patented Super Barrier Rectifier (SBR) power switching diode family to include 12 Amp and 15 Amp rated diodes in a compact package for DC/DC converter applications such as switch mode power supplies in slim laptop, netbook adapter, LCD and LED TV applications. Diode says these diodes perform better than standard Schottky rectifiers in power supply circuits.

The 12A rated SBR12U100P5 and SBR12U120P5 offer blocking voltage of 100V and 120V respectively and the 15A rated version, the SBR15U30SP5 is designed for solar PV applications where low profile bypass diodes are mounted directly beneath the glass.
Feature a forward voltage drop 0.63V for the SBR12U120P5, for a forward current of 12A at an operating temperature of 125ºC.

The package which is called PowerDI5 package is suggested for increased protection against large turn-on spikes and better overall thermal heat transfer than larger packaged rectifiers. The PowerDI5's 26mm2 footprint is 41% smaller and its height of 1.15mm is half that of the DPAK (TO252) package.
