Questions

Is there a KiCad symbol and footprint for the MMBD4148SE?

Yes. The symbol is MMBD4148:MMBD4148 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 MMBD4148SE?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the MMBD4148SE datasheet?

HT publishes it: the Datasheet link on this page opens it.

Where can I order the MMBD4148SE?

JLCPCB lists it as part C746281, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MMBD4148SE?

Parts like it in the library: the MMBD4148CC by HT, the MMBD914 by ZRE, the MMBD7000 by Diodes Incorporated and the BAV99 by Doeshare. Check their datasheets: a part that fits the footprint may still differ in its ratings.
