| SCHOTTKY RECTIFIER 21DQ06 2 Amp DO-41 Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM VF TJ @ 2 Apk, TJ = 125C range Description/Features Units A V V C The 21DQ06 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 21DQ06 2 60 0.55 - 40 to 150 CASE STYLE AND DIMENSIONS Conform to JEDEC Outline DO-204AL (DO-41) Dimensions in millimeters and inches 1 Web Site: WWW.PS-PFS.COM 21DQ06 Voltage Ratings Part number VR Max.
