onsemi · Bipolar (BJT) · SOT-416
MMBT3906TT1G from onsemi, in a SOT-416. 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 general-purpose amplifier; the datasheet specifies base cutoff current IBL at 50 nAdc maximum for VCE = −30 Vdc and VEB = −3.0 Vdc. |
| 2 | EMITTER | passive | Emitter terminal of the PNP amplifier; the emitter-base voltage rating is VEBO = −5.0 Vdc and the emitter-base breakdown voltage V(BR)EBO is −5.0 Vdc minimum. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP amplifier; the datasheet rates VCEO and VCBO at −40 Vdc and continuous collector current IC at −200 mAdc. |
