NTE268
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.
