The clamping voltage peaks at 48.3 V at the rated 83 A peak pulse current (8/20 µs waveform), which keeps downstream components inside their safe operating area during a surge event. No power line protection is built in; this is a straight unidirectional clamp for signal or DC rail use. For BOM planning, this removes the last-time-buy risk that haunts older TVS families.","metaTitle":"STMicroelectronics SM6T27A TVS Diode, 600W, DO-214AA","metaDescription":"STMicroelectronics SM6T27A TRANSIL TVS diode: 600W peak pulse power, 25.7V breakdown min, 23.1V 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":"SM6T27","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)":"25.7V","Voltage - Clamping (Max) @ Ipp":"48.3V","Voltage - Reverse Standoff (Typ)":"23.1V","Current - Peak Pulse (10/1000µs)":"83A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1e6a6ede6221d6b6009e7d617f0a0cd9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SM6T27A/alternatives.json"},"ai":{"faq":[{"question":"Is SM6T27A suitable for 24V systems?","answer":"Yes.
