DTC144EM from TECH PUBLIC, in a SOT-723. 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 (input) of the NPN digital transistor, connected through the built-in series resistor R1 with base-emitter resistor R2. |
| 2 | EMITTER | power_in | Emitter (ground) of the transistor; connects to circuit ground. |
| 3 | COLLECTOR | output | Collector (output) of the transistor; VCEO and VCBO rated 50Vdc and IC max 100mAdc. |

Package_TO_SOT_SMD:SOT-723 - 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
