The 2.1 A peak pulse current (10/1000 µs) at the clamping voltage defines the surge-handling capacity: a 732.9 V clamp on a 434 V rail means the diode absorbs the transient energy above the rail voltage, shunting it before it reaches downstream circuitry. ## Lifecycle — discontinued, no successor on record Sourcing is per-RFQ, with lot traceability and date-code confirmation at the time of quote. ## Sourcing and procurement — quoted to order As an obsolete part, 1.5KE510 is not held in regular inventory. Each lot is verified for authenticity and RoHS compliance per the original Littelfuse documentation.","metaTitle":"Littelfuse 1.5KE510 TVS Diode, 1500W, 434V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE510 Zener TVS diode, 1500W peak pulse, 434V reverse standoff, 732.9V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"459V","Voltage - Clamping (Max) @ Ipp":"732.9V","Voltage - Reverse Standoff (Typ)":"434V","Current - Peak Pulse (10/1000µs)":"2.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE510/alternatives.json"},"ai":{"faq":[{"question":"How can I order 1.5KE510 or check availability?","answer":"Submit an RFQ through this listing."},{"question":"What package does 1.5KE510 come in?","answer":"Through-hole DO-201AA axial-lead (DO-201 supplier device package).
