2SC3279-M from LGE, in a TO-92. 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 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet's absolute maximum ratings (VEBO 6 V, IC 2 A continuous, PC 750 mW) apply to the device as a whole and no pin-specific limit is stated. |
| 2 | COLLECTOR | passive | Collector terminal of the NPN transistor; it carries the collector current (2 A continuous maximum) with VCBO 30 V and VCEO 10 V ratings stated for the device. |
| 3 | BASE | passive | Base terminal of the NPN transistor, used to control the device; the datasheet specifies VEBO 6 V and a VCE(sat) test condition of IC=2 A with IB=100 mA. |
