DTA114ESA from Changjing, in a TO-92S. 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 of the TO-92S variant (DTA114ESA), the common reference for the built-in bias-resistor inverter. |
| 2 | OUT | output | Output pin; the datasheet limits output current to -50 mA (IO), with VO(on) of -0.3 V max at IO/II = -10 mA/-0.5 mA and IO(off) of -0.5 µA max at VCC = -50 V. |
| 3 | IN | input | Input pin with a built-in input resistor R1 of 7 to 13 kΩ (typ. 10 kΩ); VI(off) is -0.5 V max and VI(on) is -3 V max, and VIN is rated -40 V to +10 V. |
