The SOD housing is an absolute classic. In practice, however, it has since been surpassed by leadless chips. The obvious benefit of this approach is that the Schottky diode substrate is connected to the PCB more directly. That way, heat generated during switching or rectification operation can be dissipated more efficiently.
The SD2114S040S5R0 is but part of a large family of diodes by AVX. We are looking at the maximum for about current 5A in a housing of 2114. Of course, a wide variety of other parts are also available - if you need a Schottky diode, definitely give the SD2114S040S5R0 a chance.
