Triacs
Data Sheets
In all cases, if 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).
ALL POLARITIES ARE REFERENCED TO MT1
MT2 POSITIVE
(Positive Half Cycle)
Electrical Isolation
Teccor’s isolated triac packages will withstand a minimum high
potential test of 2500 V ac rms from leads to mounting tab or
base, over the operating temperature range of the device. The
following isolation table shows standard and optional isolation
ratings.
