FCX605TA

Diodes Incorporated · Darlington Transistors · SOT-89

FCX605TA from Diodes Incorporated, in a SOT-89. 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 NPN Darlington transistor; drive with IB = 1mA for IC = 1A (VCE(SAT) < 1.5V) and VBE(ON) max 1.7V at IC = 1A.
2 C passive Collector (middle lead, also the exposed collector tab); VCEO 120V, VCBO 140V, continuous IC 1A, peak ICM 4A.
3 E passive Emitter of the Darlington pair; emitter-base voltage VEBO limited to 10V.
