1. Insulation characteristics are guaranteed only within the safety maximum ratings, which must
be ensured by protective circuits within the application. Surface Mount Classifications is Class
A in accordance with CECC00802.
2. Refer to the optocoupler section of the Isolation and Control Components Designer’s Catalog,
under Product Safety Regulations section, (IEC/EN/DIN EN 60747-5-2) for a detailed descrip-
tion of Method a and Method b partial discharge test profiles.
