This window protects a 28V or 32V rail from transients while keeping the clamp below the 60V absolute maximum of many downstream regulators and interface ICs. Bidirectional configuration means it clamps both positive and negative surges — suited for AC signal lines, bipolar supplies, or data lines where the signal swings through zero. Single-channel, through-hole B, Axial package. ## Junction temperature range and environment fit Rated for -55°C to 175°C junction temperature. This covers automotive under-hood (125°C ambient plus self-heating), industrial motor drives, and outdoor telecom enclosures without derating the 500W pulse rating. The wide Tj range also means the reverse leakage at high temperature stays within the datasheet limit — a common failure point in cheaper TVS parts. Microchip lists the 1N6121 as Active. Sourced per RFQ against the required quantity.","metaTitle":"1N6121 Zener TVS Diode – 500W Bidirectional, 32.7V Standoff","metaDescription":"1N6121 Zener TVS diode from Microchip Technology. 500W peak pulse power, bidirectional, 32.7V standoff, 59.1V clamp.","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":"1N6121","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"B, Axial","Voltage - Breakdown (Min)":"40.9V","Voltage - Clamping (Max) @ Ipp":"59.1V","Voltage - Reverse Standoff (Typ)":"32.7V","Current - Peak Pulse (10/1000µs)":"8.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.6600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c72f565c96d1fb1ddee384734173c93c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6121 obsolete or end-of-life?","answer":"No — Microchip lists the product status as Active.
