NTE24 (NPN) & NTE25 (PNP)
Silicon Complementary Transistors
General Purpose Amplifier, Switch
Description:
The NTE24 (NPN) and NTE25 (PNP) are complementary silicon transistors in a TO237 type package
designed for general purpose medium power amplifier and switching circuits that require collector cur-
rents to 1A.
