Overview

The BF821 is an uncategorised made by NXP Semiconductors in a SOT23-3 package with 3 pins. 300V 50mA PNP High-Voltage Transistor.

PCBKit's library has its KiCad symbol (Transistors:PNP B1 E2 C3, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board.

Questions

Is there a KiCad symbol and footprint for the BF821?

Yes. The symbol is Transistors:PNP B1 E2 C3 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 BF821?

SOT23-3, with 3 pins. Its footprint is drawn on this page.

What can replace the BF821?

Parts like it in the library: the JTD78L05CA by JTD, the ESD752DBZ by Texas Instruments, the MG78L05AT3 by Megain and the MCP111-300E/TT by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
