I'm doing some automated testing of semiconductor devices. Some devices are intermittently being damaged due to transient spikes from the mux/ps.

The devices are biased at 10mV and break down at a voltage around 300mV. Would adding a schotsky diode do the trick?

Most of the diodes I see don't have bdv that low, do they have diodes with a .3V bd? Thanks.

 

Browsing thru Digikey I found a Schottky with a drop of 220mV @ 1A that may work by itself for you: UPS115UE3/TR7 Microsemi (just one of many).

This could be anything, not a clear post which is possible to answer.

Why would I give out confidential information on here about my company?

Sounds pretty clear to me. Device breaks down around 300mV so need something to block 300mV and above.

 

I would agree that building devices that "break down" (fail?) at .3 volts would be a secret. That is certainly cutting edge technology.
