Bilateral Trigger Diodes (DIACS)

Description:

The NTE6407 thru NTE6412 are bilateral trigger DIACs offering a range of voltage characteristics
from 28V to 63V. These devices are triggered from a blocking–to–conduction state for either polarity
of applied voltage whenever the amplitude of applied voltage exceeds the breakover voltage rating
of the DIAC.
