steep rising waveform (

≤1 µs rise time).

Definition of Quadrants

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.

* UL Recognized File E71639

** For 4000 V isolation, use V suffix in part number.
