Hi,

Customer is now estimating Power Dissipation for CDCLVP111-EP. Would you provide the information about θjc(top)、θjc(bottom) and θjb?

Best Regards,

Hello Toshiyuki,

You can use the numbers from the commercial datasheet for the VF package:

Those numbers will be added to the EP datasheet at the next revision.

Hi Kirby-san,

Thank you for your reply. Customer is considering power dissipation from the bottom of CDCLVP111. They are going to try thermal simulation. So, would you provide θjc(bot) spec for VF PKG?

Best Regards,

Toshiyuki

Since this package does not have a heat sink, θjc(bot) is not calculated.

HI Kirby-san,

Thank you for your reply. Which means VF PKG shouldn't be installed a heat sink on the bottom, but on the top as necessary?

Best Regards,

Toshiyuki

Hi Toshiyuki,
This is a plastic encapsulated part with plastic on the top and bottom. There is no heatsink on the bottom or top of the package. The main heatflow is through the package leads.
