Changjing · Digital Transistors · SOT-723
DTC123JM 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 | Base input of the built-in bias-resistor inverter; the datasheet limits the input voltage VIN to -5 V to +12 V (absolute maximum ratings). |
| 2 | GND | power_in | Ground reference pin for the device; the datasheet gives no separate voltage or current limit for this pin. |
| 3 | OUT | output | Collector output of the transistor; the datasheet limits output current IO to 100 mA maximum and gives a typical on-state output voltage VO(on) of 0.1 V to 0.3 V at IO/II = 5 mA/0.25 mA. |
