DTC144ECA from TECH PUBLIC, in a SOT-23. 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 | IN (BASE) | input | Base input through built-in R1 of 47kΩ (min 32.9kΩ, max 61.1kΩ) with R2 of 47kΩ to emitter; input voltage range -10 to +40 V. |
| 2 | GND (EMITTER) | power_in | Emitter, used as the ground reference of the digital transistor. |
| 3 | OUT (COLLECTOR) | output | Collector output of the NPN digital transistor, rated 30 mA output current and 100 mA maximum collector current, supply voltage -50 V. |
