TECH PUBLIC · Digital Transistors · SOT-723
DTA144EM 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 | IN | input | Input of the PNP digital transistor, connected through built-in resistor R1 (typ. 47 kΩ) to the base; absolute maximum input voltage -40 V to +10 V. |
| 2 | GND | power_in | Ground (+) terminal, connected to the emitter and to the built-in base-emitter resistor R2. |
| 3 | OUT | output | Output (collector) of the digital transistor, with maximum output current of -100 mA and supply voltage VCC of -50 V. |
