(1) Recommended operating conditions indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical Characteristics table.
(2) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125℃
(3) Maximum continuous DC current may be derated when operating with high switching frequency or high ambient temperature. See Application section for details.
