TWGMC · Digital Transistors · SOT-523
DTA143EE from TWGMC, in a SOT-523. 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 terminal of the digital transistor, which has built-in bias resistors (R1 = 4.7 kΩ typical); the datasheet gives an input voltage rating of -30 V to +10 V. |
| 2 | GND | power_in | Ground reference terminal for the transistor; the datasheet gives no separate voltage or current limit for this pin. |
| 3 | OUT | output | Output terminal of the transistor; the datasheet gives an output current rating of -100 mA maximum (IO). |
