Product Overview
The BCX55-16 is an NPN bipolar junction transistor (BJT) designed for general-purpose switching, amplification, and medium-current driver applications. It features a 60V collector-emitter voltage rating, 1A maximum collector current, and 1.3W total power dissipation. The -16 gain grade provides a defined hFE range of 100–250 at 150mA collector current.
Packaged in a SOT-89 surface-mount package, the BCX55-16 offers higher current and power capability than typical SOT-23 small-signal transistors. It is suitable for load switching, driver stages, and discrete amplifier circuits where moderate current handling and compact PCB mounting are required.
