PDTC124XU

Nexperia · Bipolar Transistors - BJT · SOT-323

PDTC124XU 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 (base) of the transistor, connected through the built-in 22 kΩ bias resistor R1; input voltage is rated from -7 V to 40 V.
2 GND power_in Ground (emitter) pin; the emitter is the reference for the input and output, with VEBO limited to 7 V.
3 O output Output (collector) pin, which is rated for a maximum output current of 100 mA and a collector-emitter voltage VCEO of 50 V.
