DTA115EL-AE3-R from UTC Unisonic 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 | GND | power_in | Ground pin, shown as GND (+) in the equivalent circuit; the datasheet gives no separate electrical limit for this pin. |
| 2 | IN | input | Input pin to the built-in bias network (R1 typically 100 kΩ, range 70 to 130 kΩ), with absolute maximum input voltage of -40 V to +10 V. |
| 3 | OUT | output | Output pin with absolute maximum output current of -20 mA; VOUT(ON) is -0.1 V typ to -0.3 V max at IOUT = -5 mA and IIN = -0.25 mA. |
