Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-323
2SC4081-R from Slkor SLKORMICRO Elec, in a SOT-323. 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 | B | input | Base of the NPN transistor; VEBO is rated 7 V maximum and VBE(sat) is 1.2 V at IC=50 mA, IB=5 mA. |
| 2 | E | passive | Emitter of the NPN transistor; the absolute maximum emitter-base voltage VEBO is 7 V and the continuous collector current rating is 150 mA. |
| 3 | C | passive | Collector of the NPN transistor; absolute maximum ratings are VCBO 60 V, VCEO 50 V, continuous IC 150 mA, and collector power dissipation PC 200 mW at Ta=25°C. |
