Is there a KiCad symbol and footprint for the SMF33A?
Yes. The symbol is Diode:SMF33A and the footprint Diode_SMD:D_SMF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMF33A?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the SMF33A datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the SMF33A?
JLCPCB lists it as part C1509585, with 149 in stock; the sellers' links on this page open their listings.
What can replace the SMF33A?
Parts like it in the library: the SMF33A by Shandong Jingdao Microelectronics, the SMF33A by GOODWORK, the SMF33A by TWGMC and the SMF33A by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
