MMBT5089LT1G from onsemi, 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 | passive | Base terminal of the NPN low-noise transistor; the emitter-base voltage rating is 4.5 Vdc (VEBO) and the maximum continuous collector current is 50 mAdc. |
| 2 | EMITTER | passive | Emitter terminal of the NPN low-noise transistor; the emitter-base voltage rating is 4.5 Vdc (VEBO), and the emitter cutoff current is specified at VEB(off) = 4.5 Vdc for the MMBT5089L. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN low-noise transistor; the collector-emitter voltage is limited to 25 Vdc (VCEO) for the MMBT5089L and the continuous collector current to 50 mAdc. |
