Notes:
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, (DIN EN
60747-5-2) for a detailed description of Method a and Method b partial discharge test profiles.
