Changjing · Bipolar (BJT) · SOT-89-3L
2SC4115 from Changjing, in a SOT-89-3L. 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 | BASE | input | Base terminal of the NPN transistor, driven with IB = 0.1 A in the datasheet's VCE(sat) test condition (IC = 2 A), and the emitter-base breakdown is rated at 6 V (VEBO). |
| 2 | COLLECTOR | passive | Collector terminal, rated for VCBO 40 V, VCEO 20 V, continuous IC 3 A, and collector power dissipation PC 500 mW. |
| 3 | EMITTER | passive | Emitter terminal, the reference for the 6 V emitter-base breakdown rating (V(BR)EBO) and the 5 V VEB test condition for ICBO/IEBO. |
