Thyristors
Damage can occur to a thyristor if the thyristor
s repetitive peak off-state voltage is
exceeded. A thyristor
s repetitive peak off-state voltage may be exceeded due to dirty
AC power mains, inductive spikes, motor latch up, etc.
Thyristor Reference Circuit
Figures 3-33 & 3-34 show two different methods of protecting a triac. In Figure 3-33, a
SIDACtor is connected from MT2 to the gate of the triac. When the voltage applied to
the triac exceeds the SIDACtor
s V
DRM
, the SIDACtor turns on, producing a gate
current which turns the triac on.
The circuit in Figure 3-34 places a SIDACtor across MT2 and MT1 of the triac. In this
instance the SIDACtor protects the triac by turning on and shunting the transient
before it exceeds the V
DRM
rating of the triac.
Regardless of the method chosen, when using a SIDACtor to protect a thyristor, the
following design considerations must be followed:
