PBSS4140U

Nexperia · Bipolar (BJT) · SOT-323

PBSS4140U 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 B passive Base terminal of the NPN transistor; peak base current IBM is 1 A (single pulse, tp ≤ 1 ms) per the limiting values.
2 E passive Emitter terminal of the NPN transistor; the device is rated for VEBO 5 V and emitter-base cut-off current IEBO of 100 nA max at VEB = 5 V.
3 C passive Collector terminal of the NPN transistor; rated for VCEO 40 V, IC 1 A continuous and ICM 2 A peak, with Ptot 250 mW (Tamb ≤ 25 °C, standard footprint) or 350 mW (1 cm² collector pad).
