J = 125°C 0.55 V T J range - 40 to 150 °C Characteristics 21DQ06 Units The 21DQ06 axial leaded Schottky rectifier has been opti- mized for very low forward voltage drop, with moderate leakage. Typical applications are in switching power sup- plies, 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 Description/Features Dimensions in millimeters and inches Conform to JEDEC Outline DO-204AL (DO-41) CASE STYLE AND DIMENSIONS DO-41 Web Site: WWW.PS-PFS.COM
