That margin matters when the rail sits at 40V nominal with a 5% tolerance — the TVS stays off during normal operation and only fires when a transient pushes the line above 44.4V. The 71.4V max clamping voltage at 8.4A peak pulse current defines the voltage the downstream circuitry must survive; a 40V-rated capacitor on that rail would need a higher voltage rating to ride through the clamp event. ## Active production, Tape & Reel delivery Microchip lists the SMBJ40CE3/TR13 as Active.","metaTitle":"SMBJ40CE3/TR13 – Microchip 600W Bidirectional Zener TVS","metaDescription":"SMBJ40CE3/TR13 Microchip Zener TVS diode, 40V standoff, 600W peak pulse, bidirectional, DO-214AA (SMB) package, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SMBJ40","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMBJ (DO-214AA)","Voltage - Breakdown (Min)":"44.4V","Voltage - Clamping (Max) @ Ipp":"71.4V","Voltage - Reverse Standoff (Typ)":"40V","Current - Peak Pulse (10/1000µs)":"8.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f566c62ad8bf6be9ecf452f6999d0b7a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ40CE3%2FTR13/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative to SMBJ40CE3/TR13 in the same family?","answer":"The SMBJ40 series includes unidirectional and bidirectional variants in the same DO-214AA package.
