1 In accordance with UL 1577, each ADuM1250/ADuM1251 is proof tested by applying an insulation test voltage ≥ 3000 V rms for 1 second (current leakage detection

limit = 5 μA).

2 In accordance with DIN V VDE V 0884-10, each ADuM1250/ADuM1251 is proof tested by applying an insulation test voltage ≥ 1050 V peak for 1 sec (partial discharge

detection limit = 5 pC). The asterisk (*) marking branded on the component designates DIN V VDE V 0884-10 approval.
