BC846BDW from YFW, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | E1 | passive | Emitter of transistor TR1; Emitter-base voltage rating is 6 V for BC846DW. |
| 2 | B1 | input | Base of transistor TR1; DC current gain hFE is 200 min to 450 max for the B grade at VCE = 5 V, IC = 2 mA. |
| 3 | C2 | passive | Collector of transistor TR2; pin 3 is drawn on the same side as pin 1, and the datasheet lists it only as Collector (no maximum collector current or voltage stated per pin beyond IC = 100 mA and VCEO = 65 V for BC846DW). |
| 4 | E2 | passive | Emitter of transistor TR2; Emitter-base voltage rating is 6 V for BC846DW. |
| 5 | B2 | input | Base of transistor TR2; DC current gain hFE is 200 min to 450 max for the B grade at VCE = 5 V, IC = 2 mA. |
| 6 | C1 | passive | Collector of transistor TR1; collector current is rated 100 mA continuous (200 mA peak) and VCEO is 65 V for BC846DW. |
