Dear Communities,

Could you let us know the measurement position to measure case temperature with thermocouple ?

Hello Yoshimura-san,

Thank you for posting on Infineon Forums.

When measuring case temperature, the thermocouple needs to be as close to the center of the heat pad as possible.
As in:

5460.attach

Here you can see that the thermocouple is attached to the center.
In the case of the device being attached to a PCB or heatsink, a path should be carved for the thermocouple to reach the head pad of the device.
When attaching the thermocouple, use a highly thermally conductive adhesive.

Best regards,
Pablo
