With a minimum breakdown voltage of 12.35V, the device triggers before the 18.2V clamp, ensuring the protected load sees minimal overvoltage during a surge event. ## Peak pulse current and clamping performance The 82.4A peak pulse current rating (10/1000µs) defines the surge capacity for direct lightning strikes or inductive kickback from motors and solenoids. At 1500W peak power, this TVS can absorb repetitive pulses as long as the junction temperature stays within the -55°C to 175°C limit. The 18.2V clamping voltage at Ipp ensures that downstream semiconductors rated for 20V or higher survive the clamped transient without secondary protection. ## Active production – no obsolescence risk No end-of-life notice or successor has been issued, so this part remains a safe choice for new designs and ongoing production.","metaTitle":"1N6145A Zener TVS Diode – 1500W, 9.9V Standoff, Active","metaDescription":"1N6145A Zener TVS from Microchip: 1500W peak pulse power, 9.9V reverse standoff, 18.2V clamping, -55°C to 175°C.","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","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"12.35V","Voltage - Clamping (Max) @ Ipp":"18.2V","Voltage - Reverse Standoff (Typ)":"9.9V","Current - Peak Pulse (10/1000µs)":"82.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"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":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/1N6145A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/1N6145A when reusing this data.
