Buyers should plan for a last-time buy or identify a drop-in replacement from the same 1.5KE family. Through-hole axial package — confirm the lead spacing and hole diameter on your PCB before committing; the axial form factor is straightforward to hand-solder or wave-solder.","metaTitle":"1.5KE10ARL4 onsemi Zener TVS Diode – Obsolete","metaDescription":"onsemi 1.5KE10ARL4 Zener TVS, 1500W peak pulse, 8.55V standoff, DO-201AD axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"onsemi","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":"eol_hot","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)":"9.5V","Voltage - Clamping (Max) @ Ipp":"14.5V","Voltage - Reverse Standoff (Typ)":"8.55V","Current - Peak Pulse (10/1000µs)":"103A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/717ad1fc0ab391931f54c66e75e89e87.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE10ARL4/alternatives.json"},"ai":{"faq":[{"question":"How can I order the 1.5KE10ARL4 or check stock?","answer":"The 1.5KE10ARL4 is obsolete per onsemi.
