Power Dissipation Characteristics
1. The package of WPM2341 is SOT23-3, surface mounted on FR4 Board using 1 in sq pad sizeˈ
2 oz CuˈR șJA is 125 ć/W.
2. The power dissipation PD is based on TJ(MAX)=150°C, and the relation between TJ and PD is TJ = Ta +
R șJA* PD , the maximum power dissipation is determined by R șJA .
3. The R șJA is the thermal impedance from junction to ambient, using larger PCB pad size can get
smaller R șJA and result in larger maximum power dissipation.
125 ć/W when mounted on
a 1 in2 pad of 2 oz copper.
