Slkor(SLKORMICRO Elec.) · Bipolar Transistors - BJT · SOT-89
2SC2881-Y from Slkor(SLKORMICRO Elec.), in a SOT-89. 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 | passive | Base terminal of the NPN transistor; the datasheet rates base current IB at 160 mA maximum and the emitter-base breakdown voltage VEBO at 5 V. |
| 2 | Collector | passive | Collector terminal; the datasheet rates continuous collector current IC at 800 mA, with VCBO and VCEO at 120 V and collector power dissipation PC at 500 mW. |
| 3 | Emitter | passive | Emitter terminal, the reference for the collector-emitter and base-emitter ratings; the datasheet rates VEBO at 5 V. |
