MMSTA14-7-F

Diodes Incorporated · Darlington Transistors · SOT-323

MMSTA14-7-F from Diodes Incorporated, in a SOT-323. 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 of the NPN Darlington pair. Drive with a small base current to switch or amplify collector current up to 300 mA; VBE(SAT) up to 2.0 V at IC = 100 mA.
2 E passive Emitter of the NPN Darlington pair. Common-emitter return path; VEBO limit 10 V.
3 C passive Collector of the NPN Darlington pair. VCBO = 30 V, VCEO = 30 V, IC = 300 mA continuous; VCE(SAT) up to 1.5 V at IC = 100 mA, IB = 100 uA.
