DTC115EE from Changjing, 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 pin of the inverter; input voltage is rated -10 V to +40 V, with VI(off) max 0.5 V and VI(on) min 3 V. |
| 2 | GND | power_in | Ground pin of the device, serving as the common reference for the input and output. |
| 3 | OUT | output | Output pin with output current rated 100 mA maximum and VO(on) max 0.3 V at IO=5 mA. |
