# M8050

**BORN** · Bipolar (BJT) · SOT-23

M8050 from BORN, 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, which drives the device; the datasheet gives VBE(sat) of 1.20 V max at IC=800 mA, IB=80 mA. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet gives an emitter-base breakdown voltage V(BR)EBO of 6 V minimum at IE=100 uA, IC=0 and a maximum emitter-base voltage VEBO of 6 V. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; the datasheet limits are VCBO 40 V, VCEO 25 V, continuous collector current IC 0.8 A, and collector dissipation PC 0.2 W. |
