Changjing · Bipolar (BJT) · TO-252-2(DPAK)
2SC3303 from Changjing, in a TO-252-2(DPAK). 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 | NPN base terminal; the datasheet gives VBE(sat) of 1.2 V at IC=3 A, IB=150 mA and the emitter-base rating VEBO of 7 V. |
| 2 | COLLECTOR | passive | NPN collector terminal; the absolute maximum ratings are VCBO 100 V, VCEO 80 V, IC 5 A and PC 1 W, with Tj 150 °C. |
| 3 | EMITTER | passive | NPN emitter terminal; the datasheet gives the emitter-base breakdown voltage V(BR)EBO of 7 V minimum at IE=100 µA. |
