Notes:
a. Based on T C = 25 °C.
b. Surface mounted on 1" x 1" FR4 board.
c. t = 10 s.
d. 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.
e. Rework conditions: manual soldering with a soldering iron is not recommended for leadless components.
f. Maximum under steady state conditions is 70 °C/W.
