Electrical Isolation
Teccor’s isolated SCR packages will withstand a minimum high
potential test of 2500 V ac rms from leads to mounting tab over
the device's operating temperature range. The following table
shows standard and optional isolation ratings.
* UL Recognized File #E71639
** For 4000 V isolation, use “V” suffix in part number.
