The "R" or "M" package rating is intended for high

surge condition use only and not recommended

for >32A (AV) continuous current use since narrow

pin leads depending on lead length can exceed

PCB solder melting temperature. "W" package is

recommended for >32A (AV) continuous current

requirements.
