D1 is now a B140, which is a MacroFab house part. It's actually a bit more expensive from distributors than the SS14FL, but the lack of a labor charge makes it quite a bit cheaper for PCBA. It's also larger, so in order to fit the new part, I moved it between Q2 and J1. This is possible because… Q2 is now a DMP3017SFG. This is a cheaper, smaller, and less over-specified MOSFET which should be fine for the job of controlling the PD Buddy Sink's output. It uses a proprietary Diodes Inc. package whose footprint I contributed to KiCad's library. Because the new MOSFET is so much smaller than the old one, I was able to fit it close to the board edge where R9 used to be. The whole output circuit has been rearranged, and I like its layout a lot more now. Also, the new position of D1 allowed me to move a bunch of reference designators closer to their footprints, which is nice.
