Complementary power Darlington transistors
Features
■ Low collector-emitter saturation voltage
■ Complementary NPN - PNP transistors
Applications
■ General purpose linear and switching
Description
The devices are manufactured in planar
technology with “base island” layout and
monolithic Darlington configuration. The resulting
transistors show exceptional high gain
performance coupled with very low saturation
voltage.
