BCX56

The Nexperia BCX56 is an NPN medium power transistor suitable for various electronic applications, particularly as driver stages in audio and video amplifiers. This transistor is housed in a compact SOT-89 (TO-243AA) surface-mount package, facilitating integration into compact designs.

Key electrical characteristics include a maximum collector-emitter breakdown voltage (VCEO) of 80V and a continuous collector current (IC) of up to 1A. It exhibits a typical DC current gain (hFE) ranging from 63 to 250 depending on the specific variant and operating conditions. The transition frequency (fT) reaches a minimum of 130MHz at 10mA collector current and 5V collector-emitter voltage.

With a maximum power dissipation of 1.3W at 25°C ambient temperature and a junction temperature up to 150°C, the BCX56 is designed for reliable operation within specified thermal limits. Its thermal resistance from junction to ambient is 94 K/W when mounted on a printed-circuit board with adequate collector pad area.

This component is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1. The SOT-89 package is suitable for surface mounting, offering efficient heat dissipation for medium power applications.
