The 57.7A peak pulse current at the 26V clamping voltage means a 16V nominal rail can ride through a 57.7A surge before the clamp forces the voltage to 26V, protecting downstream silicon rated at 30V abs-max. The reverse standoff voltage is 16V, breakdown minimum is 17.8V, and maximum clamping is 26V at Ipp. For a 12V automotive battery line (nominal 13.8V, transient to 16V), this part starts conducting at 17.8V — it stays off during normal operation and only clamps during a load-dump or inductive kick. The single unidirectional channel means the cathode goes to the protected rail and the anode to ground; reverse-polarity events forward-bias the junction and the part conducts as a Schottky until the fuse opens. ## Automotive grade and operating envelope The 1.5SMBJ series is the standard 1500W SMB TVS family from Bourns; the 1.5SMBJ16A is the 16V standoff variant.","metaTitle":"Bourns 1.5SMBJ16A TVS Diode, 1500W, 16V Standoff, DO-214AA","metaDescription":"Bourns 1.5SMBJ16A automotive TVS diode, 1500W peak pulse power, 16V reverse standoff, AEC-Q101 qualified, DO-214AA SMB package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Bourns Inc.","Type":"Zener","Series":"Automotive, AEC-Q101, 1.5SMBJ","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AA, SMB","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMBJ","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)":"17.8V","Voltage - Clamping (Max) @ Ipp":"26V","Voltage - Reverse Standoff (Typ)":"16V","Current - Peak Pulse (10/1000µs)":"57.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2565","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ee1fb175d38950cd5a23672129674f6e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMBJ16A/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/bourns-inc/1.5SMBJ16A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/bourns-inc/1.5SMBJ16A when reusing this data.
