Gate Characteristics
Teccor triacs may be turned on in the following ways:
Definition of Quadrants
•
In-phase signals (with standard AC line) using Quadrants I
and III
Electrical Isolation
Teccor’s isolated alternistor packages withstand a minimum high
potential test of 2500 V ac rms from leads to mounting tab, over
the operating temperature range of the device. The following iso-
lation table shows standard and optional isolation ratings.
•
Application of unipolar pulses (gate always negative), using
Quadrants II and III with negative gate pulses
In all cases, if maximum surge capability is required, gate pulses
should be a minimum of one magnitude above minimum IGT rating
with a steep rising waveform (?1 µs rise time).
If QIV and QI operation is required (gate always positive), see
Figure AN1002.8, “Amplified Gate” Thyristor Circuit.
