PBSS4240T

Nexperia · Bipolar (BJT) · SOT-23

PBSS4240T from Nexperia, 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 B passive Base terminal of the NPN transistor; the datasheet limits peak base current IBM to 300 mA (single pulse, tp ≤ 1 ms).
2 E passive Emitter terminal of the NPN transistor; the datasheet limits emitter-base voltage VEBO to 5 V (open collector).
3 C passive Collector terminal of the NPN transistor; the datasheet limits collector-emitter voltage VCEO to 40 V, collector current IC to 2 A and peak collector current ICM to 3 A.
