Changjing · Bipolar (BJT) · SOT-523
2SC5585 from Changjing, in a SOT-523. 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; drives the device with base current (IB = 10 mA is the test condition for VCE(sat) at IC = 200 mA). |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; VEBO maximum is 6 V and the emitter-base breakdown is specified at IE = 10 µA. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; rated for VCBO 15 V, VCEO 12 V and continuous collector current IC 0.5 A. |
