2SC3303-Y from TOSHIBA, in a TO-251-3. 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; emitter-base voltage limited to 7 V (VEBO) and base current to 1 A (IB). |
| 2 | C | passive | Collector, also the heatsink tab; VCEO 80 V, VCBO 100 V, IC 5 A DC and 8 A pulsed. |
| 3 | E | passive | Emitter, the common terminal of the NPN transistor. |
