Overview
The 1N4148 is a diodes General Purpose made by STMicroelectronics in a DO-35 package with 2 pins. DO-35 Diodes - General Purpose ROHS.
PCBKit's library has its KiCad symbol (Diode:1N4148, from KiCad's library) and its footprint (Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C13769).
