TIP126

TIP120, TIP121, TIP122 TIP125, TIP126, TIP127 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. 3 2 1 TO-220 Figure 1.
