The
sidac
is
a
silicon
bilateral
voltage
triggered switch with greater power-handling
capabilities
than
standard
diacs.
Upon
application of a voltage exceeding the sidac
breakover voltage point, the sidac switches on
through a negative resistance region to a low
on-state voltage. Conduction continues until
the current is interrupted or drops below the
minimum holding current of the device.
CERAMATE offers a voltage range of 95 V to
330 V in DO-15 package.
CERAMATE’s sidacs feature glass passivated
junctions to ensure a rugged and dependable
device
capable
of
withstanding
harsh
environments.
Variations of devices covered in this data
sheet
are
available
for
custom
design
applications. Consult the factory for more
information.
