It is a single unidirectional channel — the cathode band marks the anode-to-ground orientation. Power line protection is not supported (the device is not rated for continuous AC mains clamping). ## Sourcing an obsolete TVS — what to expect With an Obsolete lifecycle status, the 1.5KE210A is no longer manufactured by Littelfuse. Availability is limited to existing surplus stock held by independent distributors — each lot is date-code specific and confirmed at RFQ. For a BOM line that requires this exact clamp voltage and package, the procurement path is a broker or surplus channel. If a board spin is acceptable, a parametric match (1500W, DO-201, 210 V standoff) from a current-production series is the longer-term alternative — but no pin-compatible second-source is documented here.","metaTitle":"1.5KE210A Littelfuse Zener TVS, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE210A Zener TVS diode, 1500W peak pulse power, DO-201 axial package.","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)":"-","Voltage - Clamping (Max) @ Ipp":"-","Voltage - Reverse Standoff (Typ)":"-","Current - Peak Pulse (10/1000µs)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the peak pulse power rating of the 1.5KE210A?","answer":"The 1.5KE210A is rated for 1500W (1.5kW) peak pulse power, typical for a 1 ms/10 µs waveform in the 1.5KE series.
