# 2SC4672-R

**Slkor SLKORMICRO Elec** · Bipolar (BJT) · SOT-89

2SC4672-R 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 | input | Base terminal of the NPN transistor; the datasheet rates emitter-base voltage VEBO at 6 V and gives VBE(sat) of 1.2 V at IC=1 A, IB=50 mA. |
| 2 | Collector | passive | Collector terminal of the NPN transistor, rated for 2 A continuous collector current, 50 V VCEO, 60 V VCBO and 500 mW collector power dissipation. |
| 3 | Emitter | passive | Emitter terminal of the NPN transistor; the emitter-base breakdown voltage is listed as 6 V in the absolute maximum ratings. |
