The TO-251 and TO-252 are just the component package type as can been seen in this [https://www.datasheetq.com/03N60C3-Datasheet-PDF-Infineon|link]
The one in your device is a 03N60C3 in a TO-252 package
See the component connections to the board - TO-251 all 3 legs are on one side The TO-252 has 2 on one side and it looks like the case may be connected on the other side.
