DSS4160T-7

Diodes Incorporated · Bipolar Transistors - BJT · SOT-23

DSS4160T-7 from Diodes Incorporated, 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 input Base of the NPN transistor; drives IC up to 1A continuous (2A peak), with absolute maximum base current IB of 300mA (IBM 1A peak) and VEBO of 5V.
2 E passive Emitter of the NPN transistor; maximum emitter-base voltage VEBO is 5V.
3 C passive Collector of the NPN transistor, the single lead on one side of the package; VCEO 60V, VCBO 80V, IC 1A continuous and ICM 2A peak.
