DSS5140U-7

Diodes Incorporated · Bipolar (BJT) · SOT-323

DSS5140U-7 from Diodes Incorporated, 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 input Base of the PNP transistor; bottom-left lead in the top-view pin-out, with VEBO limited to -5V and peak base current IBM of -1A.
2 E passive Emitter of the PNP transistor; bottom-right lead in the top-view pin-out, with emitter-base voltage rating VEBO of -5V.
3 C passive Collector of the PNP transistor; single top lead in the top-view pin-out, rated VCEO -40V, IC -1A continuous and ICM -2A peak.
