2SD1816L-R-TN3-R from UTC(Unisonic Tech), in a TO-252. 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; emitter-base voltage VEBO max 6 V. |
| 2 | C | passive | Collector of the NPN transistor; VCBO 120 V, VCEO 100 V, IC 4 A DC (8 A pulse). |
| 3 | E | passive | Emitter of the NPN transistor; current return for the collector current. |
