It is designed to clamp transients on a nominal 85.5 V continuous rail, with a minimum breakdown voltage of 95 V and a maximum clamping voltage of 178 V at the rated peak pulse current of 22.5 A (8/20 µs waveform). The 178 V clamping voltage at 22.5 A peak pulse current (8/20 µs) defines the maximum voltage the protected circuit sees during a surge event. For a 85.5 V nominal rail, this provides roughly 2× margin above the operating voltage, which is typical for protecting downstream DC-DC converters or sensitive ICs. The 600 W peak pulse power rating (10/1000 µs) is the energy-handling capability under the standard telecom surge waveform; the actual power capability scales with pulse width, so a shorter 8/20 µs event allows higher peak current. The 95 V minimum breakdown ensures the device does not conduct at the nominal rail voltage, while the 85.5 V reverse standoff is the maximum continuous DC voltage the part can withstand without significant leakage. ## Package and mounting — DO-214AA SMB The SM6T100A is housed in a DO-214AA (SMB) package, a standard surface-mount outline for TVS diodes in the 600 W power class. The SMB footprint is common across the SM6T series, so a board layout designed for one voltage variant can accept others without a PCB change.","metaTitle":"STMicroelectronics SM6T100A TVS Diode, 600W, 85.5V Standoff","metaDescription":"STMicroelectronics SM6T100A TRANSIL TVS diode: 600W peak pulse power, 85.5V reverse standoff, 95V min breakdown, 178V 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":"SM6T100","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)":"95V","Voltage - Clamping (Max) @ Ipp":"178V","Voltage - Reverse Standoff (Typ)":"85.5V","Current - Peak Pulse (10/1000µs)":"22.5A (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/SM6T100A/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/SM6T100A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/SM6T100A when reusing this data.
