| Bulletin PD-2.287 rev. D 03/02 11DQ03 11DQ04 SCHOTTKY RECTIFIER 1.1 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 1 Apk, TJ = 25C range Description/Features Units A V A V C The 11DQ.. axial leaded Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. Low profile, axial leaded outline High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability 11DQ.. 1.1 30/40 225 0.55 - 40 to 150 CASE STYLE AND DIMENSIONS Conform to JEDEC Outline DO-204AL (DO-41) Dimensions in millimeters and inches www.irf.com 1 11DQ03, 11DQ04 Bulletin PD-2.287 rev.
