Request to share below data for PN 8407301EA: Thermal resistance, Junction to Ambient and power dissipation

0 Owen Westfall 2 months ago

Hi Sri,

We do not have the Theta JA data on hand. I've made a request for that. The turn around time for the simulations is usually 2 weeks.

as for the power dissipation that can be calculated once I get that to you using [FAQ] Where do I find maximum power dissipation for a device?

Regards,

Owen
