235 real KiCad boards from open-source hardware repositories, prepared as a placement and routing benchmark

The BC546C is a bipolar made by DIOTEC in a TO-92 package with 3 pins. 100mA 15nA 300MHz 420 600mV 65V NPN TO-92 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BC546, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-92_Inline, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3201530). 1 open-source board in 1 repository on GitHub use it.
| Pin | Name | Type |
|---|---|---|
| 1 | C | Passive |
| 2 | B | Input |
| 3 | E | Passive |

The symbol is Transistor_BJT:BC546 and the footprint Package_TO_SOT_THT:TO-92_Inline, both drawn on this page. PCBKit places them on a board for you when you design with it.
TO-92, with 3 pins. Its footprint is drawn on this page.
DIOTEC publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C3201530, with 0 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the S8050 by JSMSEMI, the S8550 by JSMSEMI, the 2N3904 by JSMSEMI and the 2N3904BU by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
