1
Maximum continuous power is derated linearly from 100% of maximum @ 40 °C to 75% of maximum @ 55 °C.
2
Based on minimum operating resistance, 0.08 Ω for 100W and 0.04 Ω for 200W. This means that below 1.6 V, the rated
current decreases linearly based on the rate of the respective minimum operating resistance.
