(1) These devices are mounted on an JEDEC low-k board (2-oz. traces on surface), (The table is assuming that the maximum junction
temperature is 120°C). The power pad on the device must be soldered down to the power pad on the board if best thermal performance
is needed.
(2) This device is mounted on a JEDEC JESO51.5 high-k board (2 signal, 2 plane). The values assume a maximum junction temperature of
120°C.
