WPM6 Power Dissipation Characteristics. The package of WPM6 is DFNx-6L, surface mounted on FR4 Board using in sq pad size ozcu R JA is 84 /W, surface mounted on FR4 Board using minimum pad size ozcu R JA is 7 /W.. The power dissipation PD is based on TJ(MAX)=5 C, and the relation between TJ and Pd is TJ = Ta + R JA* PD, the maximum power dissipation is determined by R JA.. The R JA is the thermal impedance from junction to ambient, using larger PCB pad size can get smaller R JA and result in larger maximum power dissipation. 84 /W when mounted on a in pad of oz copper 75 /W when mounted on a minimum pad of oz copper http://www.willsemi.com Page 6 Dec, Rev.
