Survival of the LT8210 under the conditions defined in ISO 16750-2 and ISO 7637-2 tests

Category: Datasheet/Specs
Product Number: LT8210

I am designing a power supply with an input voltage between 9 V and 36 V and have come across your LT8210. This is a power supply for an automotive product, so it is important that it complies with ISO 16750-2 and ISO 7637-2 standards.

The LT 8210 seems perfect for this purpose, but I have some doubts about the product's survival in some of the tests defined in the ISO 7637-2 standard. For example, test pulse 1 in ISO 7637-2 could reach a reverse polarity voltage much higher than the -40V reverse polarity protection specified in the LT8210 datasheet. The same is true for test pulse 3a in ISO 7637-2.

Something similar occurs with pulse 3b, but in this case the limit is at the upper end of the range, i.e., this test defines, for a 24V automotive system, a positive pulse greater than that supported, according to the datasheet, by the LT8210.

All these pulses are short-duration pulses, so I understand that they can be replaced with external passive components, but I would like to be sure before starting to simulate.

Thank you very much in advance.
