Surface Mounted on 1" x 1" FR4 board. b. See Solder Profile (http://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. c. Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components. * Pb containing terminations are not RoHS compliant, exemptions may apply.
