Overview
The BY399 is a diodes General Purpose made by DIOTEC in a DO-201 package with 2 pins.
PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (EasyEDA_Cloud:DO-201_BD4.5-L7.5-P11.50-D1.2-RD, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C17320862).
