Product details
Frequently asked questions
What is the difference between SMBJ78AE3/TR13 and SMBJ78A?
The base product number SMBJ78A shares the same 78V reverse standoff and 600W rating. The '' suffix on this variant indicates RoHS compliance and lead-free termination finish. The 'TR13' suffix denotes tape-and-reel packaging. Functionally identical for transient protection; the /TR13 is the production-friendly version for lead-free assembly.
