DTC143TCA from Yangzhou Yangjie Elec Tech, 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 | input | Input via built-in series base resistor R1 (3.29 to 6.11 kΩ, 4.7 kΩ typ); emitter-base voltage limit is 5 V. |
| 2 | GND | power_in | Ground, connected to the emitter of the NPN transistor. |
| 3 | OUT | output | Output at the collector of the NPN transistor, rated 50 V VCEO and 100 mA collector current. |
