Is there a KiCad symbol and footprint for the FMMT618?
Yes. 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 FMMT618?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the FMMT618 datasheet?
Slkor publishes it: the Datasheet link on this page opens it.
Where can I order the FMMT618?
JLCPCB lists it as part C18208597, with 3,764 in stock; the sellers' links on this page open their listings.
What can replace the FMMT618?
Parts like it in the library: the FMMT619TA by Diodes Incorporated, the FMMT619 by Jiangsu Changjing Electronics Technology (CJ), the ZXTN25012EFLTA by Diodes Incorporated and the LBSS5240LT1G by Leshan Radio (LRC). Check their datasheets: a part that fits the footprint may still differ in its ratings.
