DS90LT012A: Thermal Resistance

Benedict Goh

Part Number: DS90LT012A

For DS90LT012AQ, understand from the datasheet that the Theta_JC is 107degC/W.

I would like to check if this refers to the case top or case bottom?

Thanks!

Hi,

This would refer to case top.

Thanks for the prompt response and clarification!

In this case, is there a thermal resistance value for Junction-to-Case (Bottom)/ Junction-to-Lead or similar?

There is no theta JC Bottom for this device.
