The BFX89 and BFY90 are silicon planar epitaxial NPN transistors produced using

interdigitated base emitter geometry. They are particulary designed for use in wide

reverse capacitance, excellent cross modulation properties and very low noise

performance. The BFY90 is complementary to the BFR99A. Typical applications

include telecommunication and radio communication equipment.
