PAKER · Bipolar (BJT) · SOT-23
PMBT4401 from PAKER, 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 NPN transistor; the datasheet gives an emitter-base voltage rating of 6 V (VEBO) and a continuous collector current of 600 mA. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet gives an emitter-base voltage rating of 6 V (VEBO) and an emitter-base breakdown voltage V(BR)EBO of 6 V minimum. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; the datasheet gives a collector-emitter voltage of 40 V, a collector-base voltage of 60 V, continuous collector current of 600 mA, and collector power dissipation of 300 mW. |
