Mosorb™ series, Zener TVS diode, 1.5KE47ARL4G, 1500W peak pulse power, 40.2V reverse standoff, 64.8V clamping, DO-201AD axial, Tape & Reel.","salesMarkdown":"The 1.5KE47ARL4G: The 40.2 V reverse standoff voltage means the protected rail can run at 40 V nominal without the diode leaking or conducting in standby — the breakdown starts at 44.7 V minimum. The DO-201AD axial-lead package handles the 1.5 kW surge without the thermal limitations of a smaller body — the lead diameter and glass-passivated junction are sized for repetitive surge events in industrial power supplies, motor drives, and telecom rectifiers. ## Temperature range and physical fit Operating junction temperature spans -65°C to 175°C — wide enough for outdoor telecom cabinets, engine-bay electronics, or high-temp industrial enclosures where the ambient inside the box exceeds 85°C. Through-hole axial mounting in DO-201AD — the leads insert into plated through-holes on the PCB and are wave-soldered. The 0.052-inch lead diameter mates with standard 1.0 mm (0.040-inch) finished hole sizes; the body length is about 9.5 mm, so it fits between adjacent rows on a 0.100-inch pitch grid. The reel quantity is typically 1200 or 1400 pieces depending on the reel diameter; confirm the exact count at quote time.","metaTitle":"1.5KE47ARL4G Littelfuse Mosorb™ TVS, 1500W, 40.2V Standoff","metaDescription":"Obsolete Littelfuse 1.5KE47ARL4G Zener TVS diode, 1500W peak pulse, 40.2V standoff, DO-201AD axial.","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)":"44.7V","Voltage - Clamping (Max) @ Ipp":"64.8V","Voltage - Reverse Standoff (Typ)":"40.2V","Current - Peak Pulse (10/1000µs)":"23.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b2bad05ac2a782d44789dbfb00c46ecc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I source the 1.5KE47ARL4G for a BOM line?","answer":"Submit an RFQ with your target quantity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE47ARL4G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE47ARL4G when reusing this data.
