MMBT4403-TP

MCC Micro Commercial Components · Bipolar (BJT) · SOT-23

MMBT4403-TP from MCC Micro Commercial Components, 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; V(BR)EBO is 5.0 Vdc min (IE=100µAdc), and IB is 15 mAdc in the 150 mA saturation test conditions.
2 E passive Emitter of the PNP transistor; emitter-base breakdown voltage V(BR)EBO is 5.0 Vdc min.
3 C passive Collector; V(BR)CEO is 40 Vdc min, V(BR)CBO is 40 Vdc min, and Ic is rated at -600 mA.
