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