2SD1766-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 of the NPN transistor; VEBO max 5 V and VEB=4 V gives IEBO of 1 uA max. |
| 2 | Collector | passive | Collector of the NPN transistor; IC up to 2 A continuous, VCEO 32 V, VCBO 40 V. |
| 3 | Emitter | passive | Emitter of the NPN transistor, connected to the lowest potential in typical use; total power dissipation PC 0.5 W. |
