DTC143ZCA-TP from MCC(Micro Commercial Components), 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 to the built-in biasing network (R1 = 4.7 kΩ typ.), with input voltage limits of -5 V to +30 V per the maximum ratings. |
| 2 | GND | power_in | Ground reference pin, shown as GND(+) in the internal structure; the datasheet gives no separate electrical limit for it. |
| 3 | OUT | output | Output pin (collector of the internal NPN), rated for a maximum collector current of 100 mA, with VO(on) of 0.3 V max at IO = 5 mA, IO = 10 mA conditions in the electrical table, and a maximum supply voltage VCC of 50 V. |
