Kengo,
We do not spec an inrush magnitude, but rather we specify maximum current values that the device is rated (and de-rated over temperature) to handle. Figures 8-5 through 8-7 in the datasheet should provide the answers you are looking for here. These curves provide the continuous current that the device may handle over temperature (Figure 8-5), and transient current magnitude and time for 25C and 85C respectively (figures 8-6 & 8-7):
Kengo,
No, these are maximum curves. Violation of these curves will potentially damage the device. In terms of measureable signal, these are given in table 5-1:
Kengo,
Yes,. These curves show two variables: time of the "ON" pulse and duty cycle. The device is capable of surviving a 200A 1ms pulse repeatedly provided there is no current flow for another 99ms beyond this value. We also publish a "single pulse" curve that may be more relevant here since you would only experience inrush during the turn-on of the device. Note that there is actually a bit more headroom since this is assuming a one time event and not periodic signal:
