I know there are adaptors for a variety of surface mount components to help use them with through-hole boards etc. This diode package is a little unusual though - e.g:
(data sheet for a Schottky Diode)
I don't have a specific PCB layout to use it on so scratching my head for alternative approaches. I'm assuming that part of the function of the soldering pads is to act as a heatsink but I'm guessing at that if I'm honest! Does anyone have any suggestions?
