Notes:
a. Surface Mounted on 1" x 1" FR4 board.
b. t = 10 s.
c. See Solder Profile (www.vishay.com/ppg?73257). The PowerPAK SO-8 is a leadless package. The end of the lead terminal is exposed copper
(not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper tip cannot be guaranteed and is not
required to ensure adequate bottom side solder interconnection.
d. Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components.
e. Maximum under Steady State conditions is 70 °C/W.
f. Based on TC = 25 °C.

* The power dissipation PD is based on TJ(max) = 150 °C, using junction-to-case thermal resistance, and is more useful in settling the upper
dissipation limit for cases where additional heatsinking is used. It is used to determine the current rating, when this rating falls below the package
limit.
