PDTC143XT from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I | input | Input (base) pin. Drives the internal NPN base through the 4.7 kΩ series resistor R1; a 10 kΩ resistor R2 sits between base and emitter/GND. Absolute maximum input voltage V_I = -7 V to +20 V. |
| 2 | GND | passive | Ground (emitter) pin. Common return connected internally to the NPN emitter and the bottom of R2. |
| 3 | O | output | Output (collector) pin. Open-collector switching output; V_CEO max 50 V, I_O max 100 mA, peak I_CM 100 mA for tp ≤ 1 ms. |
