Is there a KiCad symbol and footprint for the S2305?
Yes. The symbol is EasyEDA_Cloud:S2305 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 S2305?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the S2305 datasheet?
SMC publishes it: the Datasheet link on this page opens it.
Where can I order the S2305?
JLCPCB lists it as part C3704130, with 0 in stock; the sellers' links on this page open their listings.
What can replace the S2305?
Parts like it in the library: the AQ05-02HTG by Littelfuse, the CDSOT23-0502B by Bourns, the ESDALD05UE2X by WeEn Semiconductors and the PESD5302F by 台湾元基. Check their datasheets: a part that fits the footprint may still differ in its ratings.
