AD-DTC114YM from Changjing, in a SOT-723. 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 of the NPN digital transistor, connected through built-in R1 (7 to 13 kΩ) to the base; input voltage range is -6 to 40 V, with VI(off) min 0.3 V and VI(on) max 1.4 V. |
| 2 | GND | power_in | Ground, connected to the emitter and to R2 of the built-in bias network. |
| 3 | OUT | output | Open-collector output of the NPN transistor, rated for 70 mA output current (100 mA peak) and 50 V supply voltage, with VO(on) max 0.3 V at 5 mA. |
