Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-23
SL3904 from Slkor SLKORMICRO Elec, 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 of the NPN transistor; emitter-base voltage limited to 6 V (VEBO) and VBE(sat) max 1 V at IC=50mA, IB=5mA. |
| 2 | EMITTER | passive | Emitter of the NPN transistor; reference terminal for VCE, with VCEO of 40 V and VEBO of 6 V. |
| 3 | COLLECTOR | passive | Collector of the NPN transistor; VCBO 60 V, VCEO 40 V, continuous collector current 0.2 A. |
