I designed a TO-3 to TO-252 adapter PCB to upgrade an amplifier I have from obsolete MOSFETs. I wanted to post it here to gauge interest from the community. I'm willing to sell these as a kit with pins or pre-soldered. Price TBD but will be reasonable.
The board has thermal vias under the TO-252 tab for heat transfer to the bottom ground plane which is exposed copper with no soldermask.

Is this dedicated to mount TO-3 devices onto PCB's designed for TO-252 or vice versa?
Best regards!

Thanks! It's for a large vibration/shaker machine for vibration testing. There are 180 of the TO3 MOSFETs on the amplifier.Looks good, which amp did you design this for?
@Kay Pirinha vice versa. See attached.
