7 / 16 page Data Sheet ADuM2250/ADuM2251 Rev. A | Page 7 of 16 DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS Note that the * marking on the package denotes DIN V VDE V 0884-10 approval for a 848 V peak working voltage. This isolator is suitable for reinforced isolation only within the safety limit data. Maintenance of the safety data is ensured by protective circuits. Table 6.
