TPS25947: Continuous operation in the clamped state

I am planning on using the TPS259472LRPW in a product that is powered by a +5VDC supply that the user provides.  The minimum V_OVC specification for the TPS259472x is 5.25V, meaning some devices will clamp the supply if the input voltage is greater than 5.25V.  I don't think this will be a problem because the voltage drop across the eFuse will be minimal, and therefore won't overheat and turn itself off.  In the clamping state, I would expect voltage regulation to be impacted, but that is OK since there are downstream regulators that will regulate the voltages for the sensitive components.

I would like to ensure the TPS259472LRPW will function continuously without faulting under the following conditions:

Power Supply: 5V +10% = 5.5V
Maximum current: 1.5 Amps
Ambient temperature: 85°C
R_θJA: 41.7°C/W (land pattern with thermal vias under the part)

The V_OVC and V_CLAMP specs are as follows:

I think there is a mistake in section 8.1 of the datasheet.  It says "overvoltage spikes are either safely clamped to the selected threshold voltage (VOVC)".  Shouldn't it be V_CLAMP instead of V_OVC?

Since V_OVC is typically 5.74V, even a +/-10% tolerance supply will not be clamped by the eFuse if V_OVC is 5.74V.  However, since V_OVC can be as low as 5.25V, and a 10% tolerance supply could output 5.5V, it is possible that some devices might clamp a 10% tolerance supply.  I've done some basic power dissipation calculations, and I don't think this will be an issue for the requirements I listed above.  But I would really appreciate it if you would let me know if I'm mistaken.

The maximum recommended junction temperature is 125°C.  Does this mean the device will operate at 125°C without a significant reduction in lifetime?  With a 5.5V input, and a clamped output voltage of 5.0V, that means 0.5V will be dropped across the eFuse.  The quiescent current is negligible and I think it can be safely omitted.

The basic power dissipation formulas I'm using are as follows:

P_D = (T_J − T_A)/R_θJA
T_J = T_A + (R_θJA x P_D)

I calculated this in Excel for T_A = 50 and 85 degrees, and 0.75W of power dissipation (1.5 Amps x 0.5V).  At 85°C ambient, T_J will be 116°C, which is within the recommended maximum.  I calculate T_J = 126.7°C for a current of 2 Amps, which is over the limit.  Here is a screenshot of my Excel sheet:

Would you please confirm that I have applied the proper analysis?  Will the TPS259472LRPW operate indefinitely given the requirements I outlined above?

Thank you for your help!
