On the ADM1270 evaluation board I am testing the protection for Vin min = 48V, Vin max = 56V. Is it good enough protection for IC if I solder SMAJ58CA on TVS D1 sites.

Hi Davorkot,
The ADM1270 can withstand an absolute maximum voltage up to 66V. The FDS9958 FET on the eval board can only withstand 60V. Your SMAJ58CA may not break down until 71.2V, which could damage…
Hi Davorkot,
The ADM1270 is a good device to for your application. The heating problem that you are encountering is with the FET. If you are using the eval board with the installed FET, then you will…
