MMBTA63-7-F

Diodes Incorporated · Darlington Transistors · SOT-23

MMBTA63-7-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 input Base of the PNP Darlington pair; drives the input stage of the composite transistor.
2 E passive Emitter of the PNP Darlington pair; Emitter-Base voltage limited to -10 V (VEBO).
3 C passive Collector of the PNP Darlington pair; VCEO -30 V, continuous collector current -500 mA.
