Its minimum breakdown voltage of 44.7V and reverse standoff of 40.2V make it suited for clamping transients on 36V to 40V nominal rails in general-purpose industrial and telecom equipment. The DO-201AD axial package (through-hole) handles the 23.2A peak pulse current at the clamping voltage of 64.8V max. Operating temperature range extends from -65°C to 175°C junction, covering harsh environments like outdoor power supplies and motor drives. ## Obsolete – Plan Replacement or Source Last-Time Buy onsemi has marked the 1.5KE47ARL4 as Obsolete. For a drop-in replacement, search for a 1.5KE47A variant in the same axial package – confirm the breakdown voltage and peak pulse power match your BOM. Submit an RFQ to check current availability and pricing for your target quantity. ## Peak Pulse Power and Clamping Performance At 1500W peak pulse power, this TVS can absorb transient energy from inductive load switching or lightning-induced surges. The clamping voltage of 64.8V at 23.2A peak pulse current means the protected rail sees no more than ~65V during a surge event – critical for downstream DC-DC converters and ICs with 60V absolute maximum ratings. No power line protection – this is a unidirectional device for DC rails, not AC mains. The single-channel configuration protects one line per part.","metaTitle":"1.5KE47ARL4 onsemi Mosorb™ Zener TVS – Obsolete, 1500W","metaDescription":"onsemi 1.5KE47ARL4 Zener TVS diode, 1500W peak pulse power, 44.7V min breakdown, 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)":"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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/717ad1fc0ab391931f54c66e75e89e87.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does 1.5KE47ARL4 come in?","answer":"DO-201AD axial, through-hole mounting.
