2SC4115S
Changjing · Bipolar (BJT) · TO-92S
2SC4115S from Changjing, in a TO-92S. 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 of the NPN transistor; the datasheet rates emitter-base voltage VEBO at 6 V max and gives emitter-base breakdown V(BR)EBO of 6 V at IE=0.05 mA. |
| 2 | COLLECTOR | passive | Collector of the NPN transistor; rated at 40 V VCBO, 20 V VCEO and 3 A collector current IC, with 300 mW collector power dissipation. |
| 3 | BASE | passive | Base of the NPN transistor; the datasheet gives DC current gain hFE of 120 to 560 at VCE=2 V, IC=100 mA, and VCE(sat) of 0.5 V max at IC=2 A, IB=0.1 A. |
