AD-BCX54-16

Changjing · Bipolar (BJT) · SOT-89-3L

AD-BCX54-16 from Changjing, in a SOT-89-3L. 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 of the NPN transistor; continuous base current is rated 100 mA (peak 200 mA) and VEBO is 5 V max.
2 COLLECTOR passive Collector of the NPN transistor, rated 1 A continuous (2 A peak), with VCEO of 45 V for the AD-BCX54 series; also connected to the tab on the package.
3 EMITTER passive Emitter of the NPN transistor, with a VEBO limit of 5 V to the base.
