PDTC124EU

Nexperia · Digital Transistors · SOT-323

PDTC124EU from Nexperia, in a SOT-323. 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 I input Input pin, which is the base of the built-in transistor and connects to the bias resistor R1 (22 kΩ); the input voltage is rated from -10 V to 40 V.
2 GND power_in Ground pin, which is the emitter of the built-in transistor and is the common reference for the input and output.
3 O output Output pin, which is the collector of the built-in transistor; the output current is limited to 100 mA.
