DTA143EKA from Foshan Blue Rocket Elec, 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 | Base | input | Base is the input of the built-in bias resistor network (R1 3.29 to 6.11 kΩ, 4.7 kΩ typ.), with input voltage VI(off) of -0.5 V max at VCC=-5.0 V and IO=-100 µA. |
| 2 | Emitter | passive | Emitter is the transistor emitter terminal, and the datasheet rates the output current IC(MAX) at -100 mA max. |
| 3 | Collector | passive | Collector is the output terminal, and the datasheet rates output voltage VCC at -50 V max and output current at -100 mA max. |
