Overview
The BAR42FILM is a schottky Diode made by STMicroelectronics in a SOT-23-3L package with 3 pins. 1 Independent 100mA 1V@100mA 30V 500nA@30V 750mA SOT-23-3L Schottky Diodes ROHS.
PCBKit's library has its KiCad symbol (Diode:BAR42FILM, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board. 7 are in stock at JLCPCB (part C283250). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the BAR42FILM?
Yes. The symbol is Diode:BAR42FILM and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAR42FILM?
SOT-23-3L, with 3 pins. Its footprint is drawn on this page.
Where is the BAR42FILM datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BAR42FILM?
JLCPCB lists it as part C283250, with 7 in stock; the sellers' links on this page open their listings.
What can replace the BAR42FILM?
Parts like it in the library: the BAT54S by UMW, the BAT54S by PANJIT International, the BAT54S-E3-18 by Vishay Intertechnology and the BAR43CFILM by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAR42FILM?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
