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.
