The DO-201AD axial package is through-hole mount, suited for high-reliability board-level protection in power supplies, industrial controls, and telecom equipment where a single robust TVS per rail is preferred over multiple SMD parts. onsemi lists the 1N6376RL4 as Obsolete. For BOM lines already in production, last-time buy or sourcing through the independent market is the practical path. ## Breakdown and clamping – what the ratings mean Minimum breakdown voltage is 14.1V – the device begins conducting at this level, so the protected rail must stay below that in normal operation. The 12V reverse standoff gives a 2.1V margin before the TVS starts to leak; that margin shrinks with temperature, so a 12V rail with tight tolerance needs a higher standoff part. If the downstream components have a 20V absolute maximum, this TVS may not protect them; a lower-clamp part is needed.","metaTitle":"1N6376RL4 Zener TVS – onsemi Mosorb™ 1500W, DO-201AD","metaDescription":"1N6376RL4 from onsemi, Mosorb™ Zener TVS, 1500W peak pulse, 12V standoff, 21.2V clamp.

We source it through our independent supply network and quote to order against your BOM line quantity. Submit an RFQ with your target quantity and preferred date code; we confirm availability and current pricing at quote time. No stock-holding claim is made – every order is sourced fresh."},{"question":"Can 1N6376RL4 be used as a replacement for 1N6376?","answer":"The base product number is 1N6376; the 'RL4' suffix indicates Tape & Reel packaging. Electrically, the 1N6376RL4 is identical to the 1N6376 bulk-pack version. If your BOM calls for 1N6376, the RL4 variant is a direct functional substitute – the only difference is the reel format. Confirm the package quantity and lead form (axial) match your assembly process."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/1N6376RL4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/1N6376RL4 when reusing this data.
