GOODWORK · Bipolar (BJT) · SOT-23
G1-MMBT5551 from GOODWORK, 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 no separate pin-level limit, so the device ratings apply (VEBO 6 V, IC continuous 600 mA). |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet gives no separate pin-level limit, so the device ratings apply (VEBO 6 V, IC continuous 600 mA). |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; the datasheet gives no separate pin-level limit, so the device ratings apply (VCBO 180 V, VCEO 160 V, IC continuous 600 mA). |
