Shikues · Bipolar (BJT) · SOT-89
FCX591 from Shikues, in a SOT-89. 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 | B | input | Base terminal of the PNP transistor; the datasheet gives no base current limit, and the emitter-base breakdown voltage V(BR)EBO is -5 V minimum at IE=-100µA. |
| 2 | C | passive | Collector terminal; limits are VCBO -80 V, VCEO -60 V, continuous collector current IC -1.0 A, and total power dissipation 500 mW at TA=25℃ when mounted on a printed circuit board. |
| 3 | E | passive | Emitter terminal; the emitter-base voltage rating VEBO is -5 V. |
