With parts that were purchased by a manufacturer and already assembled on a board, there is always some uncertainty. However, in this case, I did not see any markings that suggested the electrical specs varied from an off-the-shelf product. The datasheets for this type of STM product suggest that the base part number is included in the marking, and the remaining marks look like a date/lot code, factory location, etc. So, it’s the lack of any special markings that point to the standard electrical specs.
The only question is which exact package/case it might be, and visually it looks like the STF version. It’s always possible that the manufacturer had physical modifications made to a standard part (other than the bent leads) that had a higher power rating, but it doesn’t seem likely given the extra cost and the lack of an obvious need for it. Still, the STP package is an option if there are any concerns.
