Maximum clamping voltage at Ipp is 19.9V — downstream components must survive this peak during a 600W, 10/1000µs surge. ## Package and mounting — DO-214AA SMB Surface-mount SMB package, with the cathode identified by a band. The supplier device package is SMB.","metaTitle":"SMBJ12AONT3G onsemi TVS Diode - Obsolete, 12V Standoff","metaDescription":"SMBJ12AONT3G Zener TVS diode from onsemi, 600W peak pulse, 12V reverse standoff, DO-214AA SMB.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"SMBJ","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"600W","Base Product Number":"SMBJ","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMB","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"13.2V","Voltage - Clamping (Max) @ Ipp":"19.9V","Voltage - Reverse Standoff (Typ)":"12V","Current - Peak Pulse (10/1000µs)":"30.2A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is the SMBJ12AONT3G obsolete?","answer":"Yes, onsemi lists this part as Obsolete.
