Overview
The FDH333 is a diodes General Purpose made by onsemi in a DO-35 package with 2 pins. 1 Independent 1.15V@300mA 125V 200mA 3nA@125V 4A DO-35 Diodes - General Purpose ROHS.
PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (EasyEDA_Cloud:DO-35_BD2.0-L4.2-P8.20-D0.5-RD, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C118109). 1 open-source board in 1 repository on GitHub use it.
