Notes:
a. Surface Mounted on 1" x 1" FR4 board.
b. 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.
c. Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components.
