CONTROLLING DIMENSION: MILLIMETER www.irf.com 175 C TJ operation Low forward voltage drop (per leg) 2X O The 303CNQ center tap Schottky rectifier module series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in high current switching power supplies, plating power supplies, UPS systems, converters, free-wheeling diodes, welding, and reverse battery protection. 3.35 [.132] 3.02 [.119] Modified JEDEC Outline TO-244AB Dimensions in millimeters and (inches) 1 303CNQ...
