DESCRIPTION
The BD677, BD677A, BD679, BD679A and
BD681 are silicon epitaxial-base NPN power
transistors in monolithic Darlington configuration
mounted in Jedec SOT-32 plastic package.
They are intended for use in medium power linar
and switching applications
The complementary PNP types are BD678,
BD678A,
BD680,
BD680A
and
BD682
respectively.
