component
PSBDA40V2
Public Made by Adomby adom
Shanghai Prisemi Elec Schottky Barrier Diodes (SBD), SMA. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.
Made with KiCad 10.0 · needs KiCad 10.0 or later to open · KiCad file format 20260206
