FCX619TA

Diodes Incorporated · Bipolar Transistors - BJT · SOT-89

FCX619TA 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 transistor; drives the device, with continuous base current rated up to 500 mA.
2 C passive Collector, also connected to the exposed collector tab; rated VCEO 50 V, 3 A continuous and 6 A peak pulse current.
3 E passive Emitter of the NPN transistor; emitter-base voltage rated at 7 V maximum.
