2SC4672 from hongjiacheng, in a SOT-89. 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 | B | input | Base of the NPN transistor (pin 1 in the function diagram); VEBO max 6.0 V, and VBE(sat) max 1.0 V at IC=1.0 A, IB=50 mA. |
| 2 | C | passive | Collector of the NPN transistor (pin 2 in the function diagram); VCBO 60 V, VCEO 50 V, IC max 2.0 A. |
| 3 | E | passive | Emitter of the NPN transistor (pin 3 in the function diagram, arrow pointing out); total power dissipation 500 mW. |
