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. Document Number: 73116 www.vishay.com S10-2246-Rev.

Pulse test pulse width 300 s, duty cycle 2 %. b. Guaranteed by design, not subject to production testing. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
