SILICON DARLINGTON POWER TRANSISTORS
PNP epitaxial-base transistors in a monolithic Dalrington circuit and housed in a
TO-220 enveloppe. They are intended for output stages in audio equipment,
general amplifiers, and analogue switching application.
NPN complements are BD643, BD645, BD647, BD649 and BD651
