[edit] Summary
Cyril BUTTAY - plotted using gnuplot, source file available by email: cyril DOT buttay AT free DOT fr
This plot represents the specific resistance of MOSFETs versus their breakdown voltage. The dots are the values estimated from the datasheets of the following manufacturers: International Rectifier, ST Microelectronics, Infineon. Only the transistors in D2PAK package have been considered, with an estimated 30 mm² die size.
The "ideal" curve is the specific resistance of a single silicon layer that can withstand the given breakdown voltage
[edit] Gnuplot source
The following source was used with gnuplot 4.0 to generate the graph:

[edit] Dataset
gnuplot expects to find the data in a file named 'mos_data.txt'. As mentioned above, the data comes from various manufacturers, but I forgot to write down the corresponding devices reference numbers...

[edit] post processing
once generated by gnuplot, the eps file is converted into png by:
