BCX41QTA

Diodes Incorporated · Bipolar (BJT) · SOT-23-3

BCX41QTA from Diodes Incorporated, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base terminal of the NPN BJT. Controls collector current via base current (IB max 100mA). VBE(SAT) max 1.4V at IC = 300mA, IB = 30mA.
2 E passive Emitter terminal of the NPN BJT. Emitter-Base breakdown voltage BVEBO = 7V min; absolute max VEBO = 5V.
3 C passive Collector terminal of the NPN BJT. Collector-Emitter breakdown voltage BVCEO = 125V min; continuous collector current IC = 800mA, peak pulse ICM = 1A.
