1.2.1.2 Load cycle
The maximum peak current can be applied when the following criteria are fulfilled:
1. Duration of one peak doesn’t exceed 10 seconds
2. Mounting temperature and ambient temperature within operating range
3. Over any period of 90 seconds, the RMS value I of the current does not exceed the allowable
continuous current I :sub:` cont,max`. In the example of the current consisting of pulses with I = I
and idle phases of I = 0 between them, the maximum allowable duty cycle would be 11.1% (e.g. 10 seconds of
I = I , followed by 80 seconds of I = 0). In a more general way, this requirement can be written as
RMS,90s
peak,max
peak,max
