PJSEMI · Bipolar (BJT) · SOT-23-6
MMDT3906SG from PJSEMI, in a SOT-23-6. 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 | B1 | passive | Base terminal of PNP transistor 1; the datasheet gives only device-level ratings (VCBO -40 V, VCEO -40 V, VEBO -6 V, IC -200 mA) and no per-pin limits. |
| 2 | E2 | passive | Emitter terminal of PNP transistor 2; the datasheet gives only device-level ratings and no per-pin limits. |
| 3 | B2 | passive | Base terminal of PNP transistor 2; the datasheet gives only device-level ratings and no per-pin limits. |
| 4 | C2 | passive | Collector terminal of PNP transistor 2; the datasheet gives only device-level ratings and no per-pin limits. |
| 5 | E1 | passive | Emitter terminal of PNP transistor 1; the datasheet gives only device-level ratings and no per-pin limits. |
| 6 | C1 | passive | Collector terminal of PNP transistor 1; the datasheet gives only device-level ratings and no per-pin limits. |
