It handles a peak pulse current of 96.2A under the 10/1000µs waveform, with a clamping voltage of 15.6V at that current. The 8.4V reverse standoff means it sits transparently on a 5V or 3.3V rail, only conducting when the line exceeds that threshold. This is a through-hole axial part (B, Axial package), so it is a field-swappable component — no hot-air station needed. ## Active production, through-hole axial package The through-hole axial package (B, Axial) is a standard footprint that fits existing board layouts without redesign. Sourced per RFQ against your BOM quantity.","metaTitle":"1N6143A TVS Diode – 1500W Bidirectional Zener, Axial, Active","metaDescription":"1N6143A from Microchip Technology: 1500W peak pulse power, bidirectional Zener TVS, 8.4V standoff, 15.6V clamp at 96.2A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"B, Axial","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6143","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"10.45V","Voltage - Clamping (Max) @ Ipp":"15.6V","Voltage - Reverse Standoff (Typ)":"8.4V","Current - Peak Pulse (10/1000µs)":"96.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.9400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.microsemi.com/document-portal/doc_download/127853-1n6138-1n6173a-tvs-diode-series-datasheet","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6143A bidirectional or unidirectional?","answer":"It is a single bidirectional channel device — it clamps transients of both polarities, which is useful for AC-coupled lines or DC lines where reverse voltage may occur."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6143A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6143A when reusing this data.
