BCX56-16TF

Nexperia · Bipolar (BJT) · SOT-89-3

BCX56-16TF from Nexperia, in a SOT-89-3. 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 E passive Emitter terminal of the NPN transistor; the datasheet gives an emitter-base breakdown voltage of 5 V minimum and a VEBO rating of 5 V maximum (open collector).
2 C passive Collector terminal of the NPN transistor; the limits are IC of 1 A maximum and ICM of 2 A peak for single pulses with tp ≤ 1 ms, with VCEO of 80 V maximum (open base).
3 B passive Base terminal of the NPN transistor; the limits are IB of 200 mA maximum and IBM of 300 mA peak for single pulses with tp ≤ 1 ms.
