Package limited. b. Surface Mounted on 1" x 1" FR4 board. c. t = 5 s. d. See Solder Profile (http://www.vishay.com/ppg?73257). The PowerPAK ChipFET 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. e. Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components. f. Maximum under Steady State conditions is 110 °C/W. Document Number: 73683 S-81449-Rev.
