PDTC143ET 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 pin - connects to the base of the internal NPN transistor through the 4.7 kΩ series bias resistor R1. Drive high (>~2.5 V) to turn the transistor on. |
| 2 | GND | passive | Ground pin - connected to the emitter of the internal NPN transistor and to the low side of the internal base-emitter resistor R2 (4.7 kΩ). |
| 3 | O | output | Output pin - connected to the collector of the internal NPN transistor. Open-collector output rated 50 V VCEO, up to 100 mA sink current. |
