NTE 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 requirement, low power lamp and relay drivers and power drivers for high–current applications such as voltage regulators.
