*2 Case temperature (T C ) and heatsink temperature (T s ) is measured on the surface (mounting side) of the baseplate and the heatsink side just under the chips.
Refer to the figure on page 1 for chip location. The heatsink thermal resistance should be measured just under the chips.
*5 Pulse width and repetition rate should be such as to cause negligible temperature rise.
