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
When maximum surge capability is required, pulses should be a
minimum of one magnitude above I
GT
rating with a steep rising
waveform (
≤
1 µs rise time).
