The 28.5 V minimum breakdown gives a 2.9 V guard band above the 25.6 V standoff, which is tight enough for a 24 V rail with ±5 % regulation but leaves little margin if the rail drifts high during fault conditions.","metaTitle":"STMicroelectronics SM6T30A TVS Diode, 600W, 28.5V Breakdown","metaDescription":"STMicroelectronics SM6T30A TRANSIL™ TVS diode, 600W peak pulse power, 28.5V min breakdown, 25.6V standoff, DO-214AA SMB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"SM6T, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"SM6T30","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"28.5V","Voltage - Clamping (Max) @ Ipp":"53.5V","Voltage - Reverse Standoff (Typ)":"25.6V","Current - Peak Pulse (10/1000µs)":"75A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e6a6ede6221d6b6009e7d617f0a0cd9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T30A/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SM6T30A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SM6T30A when reusing this data.
