Utra Low On-Resistance N-Channe MOSFET SOT-23 Footprint Low Profie (<.mm) Avaiabe in Tape and Ree Fast Switching Lead-Free Description These N-Channe MOSFETs from Internationa Rectifier utiize advanced processing techniques to achieve extremey ow on-resistance per siicon area. This benefit, combined with the fast switching speed and ruggedized device design that HEXFET power MOSFETs are we known for, provides the designer with an extremey efficient and reiabe device for use in battery and oad management. A thermay enhanced arge pad eadframe has been incorporated into the standard SOT-23 package to produce a HEXFET Power MOSFET with the industry's smaest footprint. This package, dubbed the Micro3, is idea for appications where printed circuit board space is at a premium. The ow profie (<.mm) of the Micro3 aows it to fit easiy into extremey thin appication environments such as portabe eectronics and PCMCIA cards. The therma resistance and power dissipation are the best avaiabe. G S 2 IRLML2502PbF HEXFET Power MOSFET V DSS = 20V 3 D Micro3 PD - 94892A R DS(on) = 0.045Ω Absoute Maximum Ratings Parameter Max.
