DTA114EU3T106 from ROHM Semicon, in a SOT-323. 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 | GND (EMITTER) | power_in | Ground (+) terminal connected to the emitter of the built-in PNP transistor and to R2, per the DTA114EE/EU3/EKA inner circuit. |
| 2 | IN (BASE) | input | Input terminal connected to the base through built-in resistor R1 = 10kΩ (R2 = 10kΩ to emitter), with input voltage range -40 to 10 V. |
| 3 | OUT (COLLECTOR) | output | Output terminal connected to the collector, rated for output current IO of -50 mA (IC(MAX) -100 mA) and supply voltage VCC of -50 V. |
