NTE268 (NPN) & NTE269 (PNP)

Silicon Complementary Transistors

Darlington Power Amplifier

Description:

The NTE268 (NPN) and NTE269 (PNP) are silicon complementary Darlington transistors in a TO202

type package designed for amplifier and driver applications where high gain is an essential require-

ment, low power lamp and relay drivers and power drivers for high–current applications such as volt-

age regulators.
