Shikues · Bipolar (BJT) · SOT-23
FMMT591 from Shikues, in a SOT-23. 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 PNP silicon epitaxial planar transistor, for switching and amplifier use; the datasheet gives no pin-specific voltage or current limit, only device maximum ratings (for example Tj 150 ℃ maximum). |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the datasheet gives no pin-specific voltage or current limit, only device-level maximum ratings (IC -1 A continuous, per the maximum ratings table). |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; the datasheet gives no pin-specific voltage or current limit, only device-level maximum ratings (IC -1 A continuous, per the maximum ratings table). |
