MULTICOMP PRO BCX19 Silicon Epitaxial Transistor

The BCX19 is a high-current silicon epitaxial planar transistor housed in a compact SOT-23 package, designed for general-purpose amplification and switching applications. Capable of handling up to 500mA collector current at low voltages, it features a collector-base voltage of 50V and a collector-emitter voltage of 45V. With high DC current gain and low saturation voltage, it is ideal for saturated switching and driver circuits. Its affordable, surface-mount SOT-23 design ensures easy integration into various electronic systems—reliable for both industrial and consumer applications requiring efficient small-signal and power switching performance.
