Gate Characteristics
Teccor triacs may be turned on between gate and MT1 terminals
in the following ways:
•
•
In-phase signals (with standard AC line) using Quadrants I
and III
Application of unipolar pulses (gate always positive or nega-
tive), using Quadrants II and III with negative gate pulses and
Quadrants I and IV with positive gate pulses
However, due to higher gate requirements for Quadrant IV, it
is recommended that only negative pulses be applied. If pos-
itive pulses are required, see “Sensitive Triacs” section of
this catalog or contact the factory. Also, see
Figure AN1002.8, “Amplified Gate” Thyristor Circuit.
MAX QIV devices which are 0.2 V at 110 °C.
