Thank you for you response. Is it that the code matches the data sheets in the order that they are listed? My part had just A6 on it, is the compatible part 1s2838?

My diode is two pin which is closer to BAS 16 case style

It depends if your diode has 2 or 3 pins and you must identify the case used.

then, you can find the codes here :

caxapa.ru/thumbs/588912/smd-codes.pdf

For example WV4 :
BAT54S Si-diode Dual Schottky Rectifier, 30V, 200mA, Vf<1V(100mA), <5ns
