MMBT4401Q-13-F

Diodes Incorporated · Bipolar (BJT) · SOT-23

MMBT4401Q-13-F 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 passive Base terminal of the NPN transistor; the datasheet limits base current to a peak IBM of 200 mA.
2 E passive Emitter terminal of the NPN transistor; the datasheet limits emitter-base voltage to VEBO 6.0 V.
3 C passive Collector terminal of the NPN transistor; the datasheet limits collector current to 600 mA continuous (IC) and 1 A peak (ICM), with VCEO 40 V.
