MJD122 MJD127
Complementary power Darlington
transistors
Features
■ Low collector-emitter saturation voltage ■ Integrated antiparallel collector-emitter diode
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.
