Using advanced processing techniques, it achieves extremely low on-resistance per silicon area, with 45mOhm max RDS(on) at VGS=4.5V in a 2.9 x 1.6mm package. The low threshold voltage (0.6V to 1.2V) enables direct drive from 2.5V logic levels, while full enhancement at 4.5V makes it ideal for 3.3V and 5V systems. The thermally enhanced large pad leadframe provides the best thermal performance in a SOT-23 footprint. The low profile under 1.1mm suits thin portable electronics. Note: This product has been discontinued by Infineon.","working_principle":"The IRLML2502GTRPBF uses the HEXFET architecture. The hexagonal cell structure arranges MOSFET cells in a dense array. When VGS exceeds the threshold voltage, an inversion layer forms in the P-body region, creating an N-type channel connecting the N+ source to the N-epitaxial drain. Current flows vertically from drain to source. The low threshold voltage is achieved by optimizing gate oxide thickness and P-body doping for logic-level drive.","pin_description":"
