It is supplied in Cut Tape (CT) packaging. ## Obsolete – planning your next move onsemi lists the P6SMB39AT3 as Obsolete, meaning the manufacturer has discontinued production and no further orders are accepted. For existing BOM lines, you will need to secure remaining inventory or identify a drop-in replacement from the same P6SMB family or a comparable TVS series. ## Sourcing through independent channels Because the part is obsolete, new stock is not available from franchised distributors. We can source the P6SMB39AT3 through our independent supply network — quantities are verified and quoted per RFQ.","metaTitle":"P6SMB39AT3 onsemi TVS Diode – Obsolete","metaDescription":"P6SMB39AT3 from onsemi is a 600 W TVS diode in the P6SMB series, Cut Tape package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Cut Tape (CT)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"P6SMB"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3b1da25ba4b6dcf32937aa3c25e93489.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for P6SMB39AT3?","answer":"onsemi does not list a direct successor for the P6SMB39AT3.
