3.1.4 Derating curves
The following graphs show the maximum effective current in continuous S1
(In) and intermittent (Imax.) duty cycles. depending on the switching
frequency of the power transistors within a temperature range of 5 °C and
55 °C (41 °F and 131 °F).
See section, 3.1.3 LOAD DUTY CYCLES.
