BCX54-16

TWGMC · Bipolar (BJT) · SOT-89

BCX54-16 from TWGMC, 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 BASE input Base terminal of the BCX54-16 NPN transistor, with emitter-base breakdown V(BR)EBO of 5 V minimum at IE=100µA and VEBO rated at 5 V.
2 COLLECTOR passive Collector terminal, rated for IC of 1 A maximum and collector-base voltage VCBO of 45 V for the BCX54 (60 V BCX55, 100 V BCX56) within the 500 mW PC limit.
3 EMITTER passive Emitter terminal, rated with collector-emitter voltage VCEO of 45 V for the BCX54 (60 V BCX55, 80 V BCX56) and emitter-base voltage VEBO of 5 V.
