L *See Thermal Derating Curves. Note: While each output section is rated for a maximum of 20A, the maximum output per package is 60A. Electrical Characteristics (Thermal Derating Curves) How To Use These Curves Knowing maximum load current and maximum ambient temperature, use derating curves to determine required heat sink and maximum allowable base plate temperature. On left hand power dissipation curve, locate the point corresponding to maximum load current. Extend a line to the right from that point to the intersection of vertical line on right hand chart corresponding to maximum ambient temperature. From heat sink curve, read directly or extrapolate required heat sink size. Extend the line farther to the right and read on the right hand scale the maximum allowable base plate temperature.
