The pulse power graph on the left shows the peak power as a function of pulse duration for the AC01, AC01-AT series that can withstand nearly 1000 W for 1 µs square single pulse. The same type of graph can be found in the product datasheet for the other sizes up to 10 W with the AC10, AC10-AT. Additionally, to be used along with the pulse voltage graph, whichever shows lesser peak voltage, mostly applicable for high resistance values, the datasheet specifies the surge voltage curve as a function of pulse duration. The AC01, AC01-AT can handle 1100 V for pulse durations lower than 100 µs.
