How much resistance does the package of an IC contribute to the paraistic resitance of a circuit? (most applicable to mosfets)

Does it even matter? I mean, wouldn't the output impedance of the circuit itself be significantly larger than the bond wire/pin resistance? – Linkyyy Nov 29 '18 at 22:21

If your designing power circuits, mΩ's can matter nowadays, with many new power mosfets having rdsons in the mΩ range. If your selecting components, you know if you get a the same die in a D2 instead of a MLP package you'll get lower resistance. – Voltage Spike Nov 29 '18 at 23:22

That is not something that the manufacturer take into account when they specify rds in the datasheet? – Linkyyy Nov 30 '18 at 07:35

1Actually, I'm not sure on that one, probably. Either way, if your buying the same part number the package makes a difference – Voltage Spike Nov 30 '18 at 19:01
