Description:
The NTE6400 & NTE6400A Silicon Unijunction Transistors are three terminal devices having a stable
“N” type negative resistance characteristic over a wide temperature range. A stable peak point volt-
age, a low peak point current, and a high pulse pulse current make these devices useful in oscillators,
timing circuits, trigger circuits, and pulse generators where they can serve the purpose of two conven-
tional silicon or germanium transistors.
These devices are intended for applications where circuit economy is of primary importance.
