It clamps at 27.7V maximum with a 15.2V reverse standoff, handling 54.2A peak pulse current. The axial package makes it a straightforward through-hole install for board-level or point-of-entry surge protection. ## Active production — no end-of-life pressure Microchip lists the 1N6149A as Active. ## Temperature grade and environment Rated for -55°C to 175°C junction temperature, the 1N6149A suits harsh environments where commercial-grade TVS diodes would derate or fail — engine bay electronics, downhole instrumentation, avionics, and outdoor telecom enclosures.","metaTitle":"1N6149A Zener TVS Diode – 1500W Bidirectional, Axial, Active","metaDescription":"1N6149A from Microchip Technology: Zener TVS, 1500W peak pulse, single bidirectional channel, 15.2V standoff, 27.7V clamp, -55°C to 175°C, Axial package.","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":"1N6149","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"19V","Voltage - Clamping (Max) @ Ipp":"27.7V","Voltage - Reverse Standoff (Typ)":"15.2V","Current - Peak Pulse (10/1000µs)":"54.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.7950","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 1N6149A bidirectional or unidirectional?","answer":"It is a single bidirectional channel.
