Description/ Features
The 249NQ...(R) high current Schottky rectifier module series
has been optimized for low reverse leakage at high tempera-
ture. The proprietary barrier technology allows for reliable
operation up to 175擄 C junction temperature. Typical applica-
tions are in switching power supplies, converters, free-
wheeling
diodes, and reverse battery protection.
