MULTICOMP PRO MPSA44 High Voltage Transistor

This high voltage NPN epitaxial planar silicon transistor excels in general purpose applications requiring high breakdown voltages and low saturation voltages. With a collector-emitter breakdown of at least 160V, it suits lamp drivers and neon tube controls. Rated for a collector-emitter voltage of 400V, collector-base voltage of 500V, and collector current of 300mA, its thermal resistance from junction to ambient is 200°C/W. Ideal for electronic circuits demanding reliable high-voltage switching and amplification with excellent low saturation characteristics.
