Changjing · Digital Transistors · SOT-23
DTC113ZCA from Changjing, 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 | IN | input | Input pin of the built-in bias-resistor inverter stage; the datasheet's maximum input voltage rating is -5 V to +10 V. |
| 2 | GND | power_in | Ground reference pin for the transistor and bias network; the datasheet states no separate electrical limit for this pin. |
| 3 | OUT | output | Open-collector NPN output; the datasheet limits output current to 100 mA maximum and gives VO(on) of 0.3 V max at IO/II = 10 mA/0.5 mA. |
