Overview

The MMBTH81 is a bipolar made by onsemi in a SOT-23 package with 3 pins. -55℃~+150℃ 1 PNP 100nA 20V 225mW 3V 500mV 50mA 60 600MHz PNP SOT-23 Bipolar (BJT) ROHS.

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, from KiCad's library), ready for a KiCad board. 10,939 are in stock at JLCPCB (part C190349). 4 open-source boards in 3 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the MMBTH81?

Yes. The symbol is Transistors:PNP B1 E2 C3 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 MMBTH81?

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

Where is the MMBTH81 datasheet?

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

Where can I order the MMBTH81?

JLCPCB lists it as part C190349, with 10,939 in stock; the sellers' links on this page open their listings.

What can replace the MMBTH81?

Parts like it in the library: the S8050 by hongjiacheng, the SS8050 by hongjiacheng, the MMBT5551 by hongjiacheng and the MMBT5401 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the MMBTH81?

4 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
