The continuous current ratings given are for maximum 40°C (104°F), 1000m altitude and 3.0 kHz switching. Derating is required for higher switching
frequencies, ambient temperature >40°C (104°F), high altitude and parallel applications. For further information, refer to section 14.1.1 Power and
current ratings (Derating for switching frequency and temperature) on page 263.
