Mosorb™ series, Zener TVS diode, 1.5KE18ARL4G, DO-201AD axial package, 1500W peak pulse power, 15.3V reverse standoff, 25.2V clamping, unidirectional.","salesMarkdown":"## Clamping and breakdown thresholds The 1.5KE18ARL4G: The 15.3V reverse standoff means the diode stays in high-impedance below that rail voltage, making it suitable for protecting 12V or 15V DC buses where the normal operating voltage stays under the standoff threshold. Operating temperature spans -65°C to 175°C junction, covering the full industrial and military temperature envelope without derating concerns in most environments. ## Obsolete — sourcing through independent channels Littelfuse has marked the 1.5KE18ARL4G as obsolete. No official successor order code is recorded in the lifecycle data. Sourcing runs through independent surplus and broker channels — quantities are lot-specific, and availability is confirmed at the time of RFQ against the BOM line.","metaTitle":"Littelfuse 1.5KE18ARL4G Mosorb™ TVS, 1.5kW, 25.2V Clamp","metaDescription":"Littelfuse 1.5KE18ARL4G Zener TVS diode, DO-201AD axial package, 1500W peak pulse power, 15.3V standoff.","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)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.2V","Voltage - Reverse Standoff (Typ)":"15.3V","Current - Peak Pulse (10/1000µs)":"59.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b2bad05ac2a782d44789dbfb00c46ecc.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/1.5KE18ARL4G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/1.5KE18ARL4G when reusing this data.
