DESCRIPTION
The BFY84 is a six terminal device containing
two isolated silicon planar epitaxial NPN
transistors in Jedec TO77 metal case.
The good thermal tracking over a wide current
and temperature range, offers the circuit
designer matched transistors with specified
performance for differential amplifiers.
