The reverse standoff voltage of 58 V means the part draws negligible leakage below that level — your 48 V or 56 V nominal bus stays quiet. When a transient pushes the line past the minimum breakdown of 64.4 V, the diode avalanches and clamps the surge to 103 V maximum at the rated peak pulse current of 5.8 A. That clamp ceiling is the number to compare against the absolute maximum rating of your downstream MOSFET, controller, or regulator. ## Pulse power and thermal margin The product status is Active, meaning no end-of-life notice is in effect; standard lead times apply through distribution.","metaTitle":"SMBJ58E3/TR13 Zener TVS Diode – 58 V Standoff, 600 W","metaDescription":"Microchip SMBJ58E3/TR13 Zener TVS diode: 58 V reverse standoff, 64.4 V breakdown, 103 V clamp, 600 W peak pulse power, DO-214AA SMB package.","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":"SMBJ58","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMBJ (DO-214AA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"64.4V","Voltage - Clamping (Max) @ Ipp":"103V","Voltage - Reverse Standoff (Typ)":"58V","Current - Peak Pulse (10/1000µs)":"5.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2850","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f566c62ad8bf6be9ecf452f6999d0b7a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMBJ58E3%2FTR13/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMBJ58E3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMBJ58E3-TR13 when reusing this data.
