The bidirectional configuration means a single device protects both polarities — useful for AC-coupled signal lines or bipolar supply buses where a unipolar part would need an orientation check. Mounted in the common DO-214AA (SMB) surface-mount package, it fits standard pick-and-place and reflow processes. The 143V breakdown is where the device starts to avalanche; it guarantees the clamp engages before the voltage rises to a level that damages downstream silicon. The 265V clamping voltage is the worst-case peak the load sees during a surge: if your downstream components have a 300V absolute maximum, you have roughly 35V of headroom. The 600W peak pulse power rating (10/1000µs) defines the energy the part can absorb in a single event — for shorter pulses like 8/20µs the peak current capability is higher (15A), but the energy scales with pulse width. The DO-214AA footprint is widely second-sourced across the industry, so if you need to dual-source the protection function, look for a bidirectional TVS with the same standoff voltage and package from other major diode manufacturers.","metaTitle":"STMicroelectronics SM6T150CA TVS Diode, 600W, Bidirectional","metaDescription":"STMicroelectronics SM6T150CA TRANSIL™ TVS diode: 600W peak pulse power, 128V standoff, 265V clamping, bidirectional, 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":"SM6T150","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMB (DO-214AA)","Voltage - Breakdown (Min)":"143V","Voltage - Clamping (Max) @ Ipp":"265V","Voltage - Reverse Standoff (Typ)":"128V","Current - Peak Pulse (10/1000µs)":"15A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e6a6ede6221d6b6009e7d617f0a0cd9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T150CA/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy SM6T150CA and how do I get a price?","answer":"The SM6T150CA is available to order through independent distribution."},{"question":"What is the peak pulse power of SM6T150CA?","answer":"The SM6T150CA is rated for 600W peak pulse power under the 10/1000µs waveform."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SM6T150CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SM6T150CA when reusing this data.
