It clamps a 22V reverse standoff rail with a minimum breakdown voltage of 25.9V and a maximum clamping voltage of 37.5V at rated peak pulse current. The junction temperature range spans -65°C to 175°C, covering extreme thermal environments found in industrial controls, telecom rectifiers, and automotive auxiliary circuits. ## Obsolete — sourcing through independent channels onsemi lists the 1N6379 as Obsolete. Sourcing now runs through independent distribution — any available stock should be date-code verified against the original onsemi production period. The DO-201AD axial package is through-hole, which simplifies manual replacement but limits automated assembly throughput. ## Design-in note for replacement selection A direct replacement must match the 1500W peak pulse rating, 22V standoff, and unipolar clamping characteristic in DO-201AD or equivalent axial footprint. The 25.9V breakdown minimum and 37.5V clamping maximum define the protection window — any substitute must hold these thresholds to avoid overvoltage stress on the downstream circuitry.","metaTitle":"1N6379 onsemi Mosorb™ Zener TVS 1500W DO-201AD Obsolete","metaDescription":"1N6379 is a 1500W peak pulse Zener TVS from onsemi Mosorb™ series. 22V standoff, 25.9V breakdown, DO-201AD axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","Type":"Zener","Series":"Mosorb™","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6379","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"25.9V","Voltage - Clamping (Max) @ Ipp":"37.5V","Voltage - Reverse Standoff (Typ)":"22V","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b7e9ebd201a66815e17f0ecd34810bb8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for 1N6379?","answer":"onsemi has not published a direct successor for the 1N6379.
