Other Parts Discussed in Thread: TPS74401
Dear TI Team
I would like to ask about TB of UA78L12ACPK.
Our customer is trying to find TJ from the following formula.
Along with that, I have received a request from them to tell me the measurement position of TB in the following formula.
Checking the following materials, TB is measured at a position 1 mm away from the GND pin of each package of TPS74401.

Therefore, I am thinking of measuring TB at a position 1 mm away from the GND pad (red circle in the figure below) of UA78LACPK.
Is this okay?
Best Regards,
Y.Ottey
