SOIC-8 (D) and DFN-8 (DRB) packages are available taped and reeled. Add T suffix to device type (e.g. TPS28225DT) to order taped
devices and suffix R to device type to order reeled devices.
The SOIC-8 (D) and DFN-8 (DRB) package uses in Pb-Free lead finish of Pd-Ni-Au which is compatible with MSL level 1 at 255°C to
260°C peak reflow temperature to be compatible with either lead free or Sn/Pb soldering operations.
In the DFN package, the pad underneath the center of the device is a thermal substrate. The PCB “thermal land” design for this
exposed die pad should include thermal vias that drop down and connect to one or more buried copper plane(s). This combination of
vias for vertical heat escape and buried planes for heat spreading allows the DFN to achieve its full thermal potential. This pad should
be either grounded for best noise immunity, and it should not be connected to other nodes.
