Which parameters are important to decide an ESD diode suitable for VBUS?

[TNg.1]

Hi,

I found ESDA7P60-1U1M suitable for VBUS ESD protection in the link https://my.st.com/content/my_st_com/en/products/protection-devices/esd-protection.html

Last time, I did not use specific ESD diodes (like ESDA7P60-1U1M) for VBUS. The part was a general purpose ESD diode ESD051-1F4.

Please help me to specify which parameters are important to be suitable for VBUS?

Thank you,

Tom,
