Its 64.6V maximum clamping voltage at 7.7A peak pulse current (10/1000µs waveform) sets the upper bound on voltage stress that the protected circuit must survive — a key number for the board-level surge budget, not just a datasheet line. This is a unidirectional device in a through-hole axial package (B, Axial), suited for point-of-entry protection on DC power buses, industrial control inputs, and telecom line cards where a soldered lead gives mechanical standoff and thermal mass that surface-mount parts cannot match. The 64.6V clamp at 7.7A peak pulse current means that any component on the protected rail must have a breakdown rating above that level, or the TVS becomes the last line of defence. The 35.8V reverse standoff is the maximum continuous DC voltage the diode can block without conducting — design the rail at 35V or below to keep leakage negligible under normal operation. The 44.7V minimum breakdown voltage gives a 25% margin above the standoff, which is tight enough to respond fast to an overvoltage event but wide enough to avoid nuisance triggering from supply ripple. ## Active Production – Sourcing for the BOM Line Microchip lists the 1N6122A as Active — no end-of-life notice, no last-time-buy clock. Quantity breaks and lead time are confirmed at quote time; the active status means the supply chain is open and multi-source across distributors.","metaTitle":"1N6122A Zener TVS Diode – 500W, 35.8V Standoff, Axial","metaDescription":"1N6122A Zener TVS diode from Microchip Technology. 500W peak pulse power, 35.8V reverse standoff, 64.6V clamp at 7.7A.","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":"500W","Base Product Number":"1N6122","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"44.7V","Voltage - Clamping (Max) @ Ipp":"64.6V","Voltage - Reverse Standoff (Typ)":"35.8V","Current - Peak Pulse (10/1000µs)":"7.7A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.4850","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c72f565c96d1fb1ddee384734173c93c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest alternative to the 1N6122A in the same Circuit Protection family?","answer":"Within Microchip's Zener TVS line, the 1N6122A shares the same 500W rating and axial package with other standoff-voltage variants. The base product number 1N6122 covers the family; a different standoff voltage (e.g., 1N6122A vs 1N6123A) changes the clamp and breakdown thresholds. Confirm the rail voltage before substituting — the 35.8V standoff is specific to this order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6122A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6122A when reusing this data.
