FCX591TA

Diodes Incorporated · Bipolar (BJT) · SOT-89

FCX591TA 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 PNP transistor; base current is limited to -200 mA (IB) and VEBO to -7 V.
2 C passive Collector (also the exposed collector tab/pad) with VCEO of -60 V, VCBO of -80 V, continuous IC of -1 A and peak ICM of -2 A.
3 E passive Emitter of the PNP transistor; emitter-base breakdown BVEBO is -7 V minimum.
