Is there a KiCad symbol and footprint for the BAT64-04?
Yes. The symbol is Diodes:Diode Schottky x2 A1C3_A3C2 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAT64-04?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BAT64-04 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the BAT64-04?
JLCPCB lists it as part C77330, with 5,952 in stock; the sellers' links on this page open their listings.
What can replace the BAT64-04?
Parts like it in the library: the BAT54SFILM by STMicroelectronics, the ZLLS1000TA by Diodes Incorporated, the LBAT40-04LT1G by Leshan Radio (LRC) and the PMEG4010ET by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAT64-04?
3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
