1. This is allowable value up to Ta = 25qC.
Derate by Tj-a = 30qC/W above that temperature.
Tj-a = 30qC/W is the case that HA16341NT is mounted on 30% wiring density glass epoxy board
(105 mm u 76.2 mm u 1.6 mmt) and HA16341FP is mounted on a board which thermal
resistance is 23qC/W because of Tj-pin (SOP) = 7qC/W typ.
