3. Application Circuit Examples

The application circuits contain external components that are needed for over-voltage, reverse polarity, and short circuit protection.

Recommendation: Check the ZSC31150 product page www.IDT.com/ZSC31150 for other application examples given in application notes.

Note: Some application notes require a customer login—see section 9 for details.
