At that point it avalanches and clamps the surge to 353 V maximum at the rated 11.3 A peak pulse current (8/20 µs waveform). ## Peak pulse power and the waveform that defines it The 11.3 A peak pulse current figure carries an 8/20 µs waveform annotation, which is the typical IEC 61000-4-5 combination-wave generator output. That means the part is characterised for both the longer telecom surge and the faster EMC surge, so you can size it against either test level without re-rating. ## Package and temperature range for the environment The operating junction temperature range is -55°C to 150°C, which covers industrial, telecom outdoor cabinets, and under-hood automotive modules (the part is not AEC-Q101 listed in this evidence, but the temperature grade alone supports non-automotive harsh environments).","metaTitle":"STMicroelectronics SM6T200CA TRANSIL TVS, 600W","metaDescription":"STMicroelectronics SM6T200CA bidirectional TVS diode, 600W peak pulse power, 171V reverse standoff, 190V min breakdown, 353V clamping.","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":"SM6T200","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)":"190V","Voltage - Clamping (Max) @ Ipp":"353V","Voltage - Reverse Standoff (Typ)":"171V","Current - Peak Pulse (10/1000µs)":"11.3A (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/SM6T200CA/alternatives.json"},"ai":{"faq":[{"question":"Will SM6T200CA replace SM6T200A?","answer":"The SM6T200A is the unidirectional version of this same TRANSIL™ series. The SM6T200CA is the bidirectional variant. They share the same breakdown and clamping voltages and the same SMB package, but the SM6T200A has a single anode-cathode orientation while the SM6T200CA clamps both polarities. If the original design used the SM6T200A in a circuit that only sees positive-going transients, the bidirectional part will work electrically but the board may have a different silkscreen marking for polarity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SM6T200CA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SM6T200CA when reusing this data.
