The sidac from Motorola is best
compared with a triac of which the
gate connection is missing. lt switches
on whenever the voltage across it
exceeds a certain level. The polarity
of that potential is immaterial: like
a triac, the sidac works equally well
with direct and alternating voltages.
Furthermore, when the sidac is on,
it resembles a short -circuit and remains
in that state until the level of
the current drops below a certain value
(the holding current), where upon it switches off.
