TPA3255: TPA3255

Pradeep k

Part Number: TPA3255

Hi Team,

We are planning to mount Heat sink on TPA3255 IC for effective hear transfer- However we would like to clarify below points before proceeding-

What would be the max pressure/torque that can be applied on TPA3255 IC
What is the precautions to be taken care while mounting the Heatsink
What is the recommended thermal element to be applied b/w ICTPA3255 and Heatsink
The Heatsink has 1 mm gap for IC – where as IC height can vary up to 1.2mm max – ( Is 0.2 mm compression on IC is okay?)

Thanks & Regards,

Pradeep

Totally 200N press could be placed on top of the device.

Nothing particular I should say. Seldom to find damage caused by heatsink.

Thermal grease is the best choice.

Should be no problem, the EVM heatsink also has the gap of 1mm.

Totally 200 N means almost 20Kg load on top of TPA3255 - could you please re-confirm once again ?

Hi Pradeep

Yes, that is the Max value before damage.
