The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection. Easier to mount and lower profile than DO-5's 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 CASE STYLE AND DIMENSIONS Outline HALF PAK Module Dimensions in millimeters and inches www.irf.com 1 242NQ030 PD-2.281 rev.
