The Infineon IPTC019N10NM5 is part of OptiMOS 5 power MOSFET in TOLT in that TO-Leaded top side-cooling package for superior thermal performance. This innovative package combined with the key features of OptiMOS 5 technology allows best-in-class products in 100 V as well as high current rating 300 A for high power density designs. With top side-cooling setup the drain is exposed at the surface of the package and 95 percent of the heat dissipation can be promoted directly to the heatsink achieving 20 percent better RthJA and 50 percent improved RthJC compared to TOLL package. With bottom side cooling packages like TOLL or D2PAK, the heat is dissipated via the PCB to the heatsink causing high power losses.
