It clamps a transient at 59.3 V maximum when the surge current hits the rated Ipp, and its 36.8 V reverse standoff voltage means it stays out of the way on a 36 V or lower rail. Built for general-purpose circuit protection, it handles the full -65°C to 175°C junction temperature range — suitable for outdoor telecom cabinets, industrial power supplies, and automotive load-dump scenarios where the ambient can swing wide. ## Clamping voltages and the protection window The breakdown voltage (minimum 40.9 V) sits between the standoff and clamp levels. A 36.8 V rail sees no leakage at steady state; the device only conducts when the transient pushes past 40.9 V, and it holds the peak below 59.3 V. That 18.5 V window between standoff and clamp is tight enough to protect 40 V-rated downstream silicon. No power-line protection — this is a signal- or DC-rail suppressor, not for AC mains. The single unidirectional channel handles one polarity; for bipolar rails you need two devices or a bidirectional part. onsemi lists the 1N6286ARL4 as Obsolete. The DO-201AD axial package is through-hole, supplied in Tape & Reel (TR). Store the reels dry — the axial leads are solderable without special bake if kept in original packaging, but moisture-sensitive labels on the reel should be checked before reflow.","metaTitle":"1N6286ARL4 Zener TVS Diode – onsemi Mosorb™ 1.5kW DO-201AD","metaDescription":"onsemi 1N6286ARL4 Mosorb™ Zener TVS, 1.5kW peak pulse, 36.8V standoff, 59.3V clamp.

The 'RL4' suffix indicates Tape & Reel packaging. If your BOM calls for the RL4 reel format, a plain 1N6286A in bulk tube or ammo pack is electrically identical but may require a different feeder setup. Confirm the package suffix matches your assembly process."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1N6286ARL4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1N6286ARL4 when reusing this data.
