The 24.4V clamping ceiling keeps downstream 20V-rated ICs within their absolute maximum during an ESD or inductive-load dump. ## SOD-123F package and temperature range Housed in the SOD-123F surface-mount package (supplier device package SOD-123FL), the SMF15AT1 suits automated PCB assembly.","metaTitle":"SMF15AT1 Zener TVS – onsemi, 15V Standoff, Obsolete","metaDescription":"SMF15AT1 from onsemi: 15V reverse standoff Zener TVS, 200W peak pulse, SOD-123F.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"SOD-123F","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"200W","Base Product Number":"SMF","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SOD-123FL","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"16.7V","Voltage - Clamping (Max) @ Ipp":"24.4V","Voltage - Reverse Standoff (Typ)":"15V","Current - Peak Pulse (10/1000µs)":"8.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2a75efa97668a7986501689a818d2f57.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order SMF15AT1 or check availability?","answer":"The SMF15AT1 is obsolete.
