Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. Surge protection devices are normally selected according to the working peak reverse voltage (V_RWM), which should be equal or greater
than the DC or continuous peak operating voltage level.
