BCX56

The BCX56 is a single NPN bipolar junction transistor manufactured by CJ, optimized for use in general-purpose amplification and switching circuits. This component delivers a maximum DC collector current of 1A and can handle peak currents up to 1.5A, making it suitable for moderate-power applications.

Electrical characteristics include a collector-emitter voltage rating of 80V and a collector-base voltage of 100V. The device maintains a low saturation voltage of 0.5V at 500mA collector current, ensuring efficient operation in digital logic and driver stages. With a transition frequency of 130MHz, it remains effective for medium-frequency signal processing tasks.

Thermal management is supported by a total power dissipation rating of 1.3W at 25°C ambient temperature, alongside a junction-to-ambient thermal resistance of 94K/W. The operating and storage temperature range spans from -65°C to +150°C, providing robust performance across demanding industrial environments.

Packaged in a compact SOT-89 (TO-243AA) surface-mount case, the BCX56 facilitates automated PCB assembly while maintaining reliable electrical connections. Its standardized pinout and mechanical dimensions simplify integration into existing board layouts without requiring significant redesign.
