Hello, I would like to use in my design the Transil TVS STIEC45-28ACS and SM30T33CAY as the similar parts. One will be the second source for another. My question is: whether I can use one instead other and what are the difference's between them? Both will be used for transient protection accordingly IEC 61000-4-5 for 8/20 pulse with the peak current 500 ADC. What part is better: with more current as SM30TY or with less voltage drop out as STIEC45?
Thank you.
