TPS1663: Is a TVS diode required for the TPS1663?

Part Number: TPS1663

Tool/software:

Hi Team,

Is it absolutely necessary to include a TVS diode on the IN pin of the TPS16630?
We are currently designing a circuit using the TPS16630.
I'm supplying a rated 24V power source to the IN pin.
However, I observed that the voltage at the IN pin rises to around 80V the moment the overcurrent protection activates and the OUT pin turns off.
According to the EVM reference, a 33V TVS diode is inserted at the IN pin.
Is the TVS diode a necessary component to prevent the voltage surge I observed?
