The single-channel Zener-type construction protects one polarity — positive transients are shunted to ground; negative excursions forward-bias the diode and clamp at roughly 1 V. For a 13 V rail carrying sensitive logic or sensor power, this clamping margin keeps downstream devices inside their absolute-max ratings during an IEC 61000-4-5 surge event. ## Junction temperature range and package fit The DO-214AA (SMB) surface-mount package uses the standard JEDEC footprint shared by the 1.5SMBJ family.","metaTitle":"Bourns 1.5SMBJ13A TVS Diode, 13V, 1.5kW, DO-214AA","metaDescription":"Active Bourns 1.5SMBJ13A unidirectional TVS diode, 13V reverse standoff, 1.5kW peak pulse power, DO-214AA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Bourns Inc.","Type":"Zener","Series":"1.5SMBJ","Package":"Tape & Reel (TR); Cut Tape (CT)","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)":"14.4V","Voltage - Clamping (Max) @ Ipp":"21.5V","Voltage - Reverse Standoff (Typ)":"13V","Current - Peak Pulse (10/1000µs)":"69.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ee1fb175d38950cd5a23672129674f6e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMBJ13A/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Bourns provide for the 1.5SMBJ13A?","answer":"Bourns typically provides RoHS and REACH declarations for the 1.5SMBJ series; confirm the exact documentation package with the supplier at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/bourns-inc/1.5SMBJ13A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/bourns-inc/1.5SMBJ13A when reusing this data.
