Definition of Quadrants
Electrical Isolation
Teccor鈥檚 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.
Electrical Isolation
In all cases, if maximum surge capability is required, gate pulses
should be a minimum of one magnitude above minimum I
GT
rating
with a steep rising waveform (攏1 碌s rise time).
If QIV and QI operation is required (gate always positive), see
Figure AN1002.8, 鈥淎mplified Gate鈥?Thyristor Circuit.
