We frequently get questions about the applicability of our ESD and I/O solution IP for space applications. Semiconductor devices that are used at high elevation or in space need special attention during the design phase. Sofics technology has been used for a number of aerospace projects. In this article we provide more background and some example cases.
When the conventional dual diode based ESD protection is causing problems ESD designers can use one of these 6 concepts.
The most common ESD protection for I/Os consist of two diodes. To cover all the different stress combinations a rail clamp is required. In this article we discuss another option. For many interfaces a local ESD protection clamp is actually a better option.
