Max Junction Temperature

[Karlin Stutzman]

What is the max. junction temperature for the OSD335x-SM package? And, the theta-j-c if available.

[Erik Welsh]

Our System-in-Package (SiP) devices are rated for case temperature, not junction temperature as case temperature encompasses all of the components that are within a SiP.  You can find information on the thermal characteristics of the OSD3358-SM in our thermal application note:  https://octavosystems.com/app_notes/osd335x-sm-thermal-guide/

Please let us know if you have any additional questions.

Thank you. Do you have a theta-junction-to-case value for this package?

[Greg Sheridan]

Hi Karlin,

Please see sections 2 and 3 of the app note Erik pointed you to above.  It should have all of the information you need to do your calculations.

 

Thanks,

Greg

I’m being told that my analyst would prefer the theta value, instead of the psi value, as we can not exactly replicate your test conditions.

Thanks,

Question is being dealt with offline. Closing out the ticket here.

Best,

Neeraj
