Mosorb™ series Zener TVS diode, 1.5KE82ARL4G, 1500W peak pulse power, 70.1V reverse standoff, 113V clamping, unidirectional, DO-201AD axial package, Tape & Reel.","salesMarkdown":"## Obsolete — sourcing through independent channels The 1.5KE82ARL4G: For existing BOM positions or legacy designs that require this exact clamp voltage and package, the part remains available through independent surplus and broker distribution. Availability and pricing are confirmed against an RFQ; quantities are lot-specific. ## Clamping performance and the 1500W pulse rating The 113 V maximum clamping voltage at 13.3 A peak pulse current defines the voltage the protected circuit must survive; a 70.1 V reverse standoff means the diode draws negligible leakage below that rail voltage. Breakdown is specified at 77.9 V minimum — the avalanche threshold sits well above the 70.1 V standoff, so the part does not conduct during normal DC bias on a 48 V or 60 V bus. The unidirectional configuration (one channel) clamps only one polarity; a bidirectional TVS is needed for AC-coupled lines. ## Package, temperature range, and board integration Through-hole DO-201AD (axial-lead) package — the same body as the 1N6267 and P6KE families.","metaTitle":"Littelfuse 1.5KE82ARL4G Zener TVS, 1500W, DO-201AD","metaDescription":"Littelfuse 1.5KE82ARL4G Mosorb™ Zener TVS diode, 1500W peak pulse, 70.1V standoff, 113V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"Mosorb™","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-65°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"77.9V","Voltage - Clamping (Max) @ Ipp":"113V","Voltage - Reverse Standoff (Typ)":"70.1V","Current - Peak Pulse (10/1000µs)":"13.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b2bad05ac2a782d44789dbfb00c46ecc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1.5KE82ARL4G and how do I get a price?","answer":"Sourced through independent distribution channels against an RFQ.
