In accordance with UL1577, each ADuM1240/ADuM1241/ADuM1245/ADuM1246 is proof tested by applying an insulation test voltage ≥3000 V rms for 1 second

(current leakage detection limit = 5 µA).

In accordance with DIN V VDE V 0884-10, each ADuM1240/ADuM1241/ADuM1245/ADuM1246 is proof tested by applying an insulation test voltage ≥1050 V peak for

1 second (partial discharge detection limit = 5 pC). The asterisk (*) marked on the component designates DIN V VDE V 0884-10
