What voltage product should I select for NNCD breakdown voltage?

Latest Updated:11/01/2005

Question:

I plan to use the NNCD Series for noise cutting of a 5 V power supply.
Regarding the NNCD breakdown voltage, what voltage product should I select?

Answer:

What is the upper limit voltage of the power supply line you want to protect?
To determine the breakdown voltage, select an NNCD diode with a lower limit voltage that is higher than the higher limit of the power supply line.
In the case of a 5 V power supply, the NNCD 6.8V should be suitable.
