6 / 12 page ADuM1250/ADuM1251 Data Sheet Rev. F | Page 6 of 12 DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS This isolator is suitable for reinforced isolation only within the safety limit data. Maintenance of the safety data is ensured by protective circuits. The asterisk (*) marking on the package denotes DIN V VDE V 0884-10 approval for a 560 V peak working voltage. Table 6.
