IFT versus dv/dt
Triac drivers with good noise immunity (dv/dt static) have
internal noise rejection circuits which prevent false triggering
of the device in the event of fast raising line voltage tran-
sients. Inductive loads generate a commutating dv/dt that
may activate the triac drivers noise suppression circuits. This
prevents the device from turning on at its specified trigger
current. It will in this case go into the mode of “half waving” of
the load. Half waving of the load may destroy the power triac
and the load.
Figure 8 shows the dependency of the triac drivers IFT ver-
sus the reapplied voltage rise with a Vp of 400 V. This dv/dt
condition simulates a worst case commutating dv/dt ampli-
tude.
It can be seen that the IFT does not change until a commu-
tating dv/dt reaches 1000 V/
μ
s. Practical loads generate a
commutating dv/dt of less than 50 V/
μ
s. The data sheet spe-
cified IFT is therefore applicable for all practical inductive
loads and load factors.
