The Discrete PQFN package family comprises efficient devices with a wide range of input voltages, all
of which are lead-free as indicated by the PbF suffix after the part number (for example, IRFH5300PbF).
There are various sizes and outlines. The main text of this application note contains guidance applicable
to the whole range, while Appendix A contains device outlines, substrate layouts and stencil designs for
each device. For more detail about individual devices, refer to the relevant product data sheet and
package outline drawing. To simplify board mounting and improve reliability, International Rectifier
manufactures PQFN devices to exacting standards. These high standards have evolved through
evaluating many different materials and designs. Although such evaluations have yielded good results, the
recommendations in this application note may need to be adjusted to suit specific production environments.
