Chapter 3x is filled with advanced practical design information, application- oriented theory, especially for linear use of power MOSFETS, graphs and measurements, and interesting, unusual design examples. Selecting the right part is a big part of this type of engineering, and this section 3x.11 is a guide to differences and choices. -- Thanks, - Win

A few of the tables look to have an error in the last row where instead of listing IRF8xx it says IRF6xx (6 not 8) GH

And that was in the section reviewed by our copy-editor, showing it needs to be reviewed by (multiple) engineers! Keep looking! -- Thanks, - Win

Keep looking!I'd love to, but the browser crashed: ".pdf files are supported but something went wrong." Funny, it displayed it ok for a couple of seconds, then promptly fell over.

Text on file page 3, "IR also provided an additional conservative spec in its datasheets, maximum drain current at a case temperature TC = 100 deg C (also a calculated value)." The table was supposed to also be Tc = 100C, not Tj. I checked for that issue in the rest of the text. -- Thanks, - Win

I remember when IR made selenium rectifiers. -- John Larkin Highland Technology, Inc picosecond timing precision measurement jlarkin att highlandtechnology dott com http://www.highlandtechnology.com
