Electrical Isolation

Teccor’s isolated sensitive SCRs 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 other standard and optional isolation ratings.

*UL Recognized File #E71639

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