CONTROLLING DIMENSION: MILLIMETER www.irf.com 125°C TJ operation (VR < 5V) Low forward voltage drop (per leg) 2X Ø The 225CNQ center tap Schottky rectifier module has been optimized for ultra low forward voltage drop specifically for the OR-ing of parallel power supplies. The proprietary barrier technology allows for reliable operation up to 125 °C junction temperature. Typical applications are in parallel switching power supplies, converters, reverse battery protection, and redundant power subsystems. 3.35 [.132] 3.02 [.119] Modified JEDEC Outline TO-244AB Dimensions in millimeters and (inches) 1 225CNQ015 Series Bulletin PD-2.294 rev.
