ESD2CANFD24-Q1: ESD protection for 100BASE-T1 with 52V STB protection

Hi Richard,

What is a STB fault? And yes, you are correct. We only have devices that go up to 836V currently, but will clamp in the 50V and 60V range.

Hi Richard, 

Thanks for explaining. We currently don't have anything that will support 48V battery system, but we should have a solution in the first half of next year.

Hi Richard, 

Yes, stacking two diodes can be an option. When stacking, anything voltage wise will add (clamping voltage, working voltage, breakdown voltage) as well as capacitance and leakage current. ESD and surge ratings will not add, and instead be the lowest value out of the devices. 

ESD601 and ESD2CAN36 might be an option to make sure the capacitance stays low. Are there additional requirements for ESD protection?

ESD601 + ESD2CAN36:

Vrwm: 54V

Vclamp: 96V

Capacitance: 3.1pF

ESD: 15kV
