Its 1500W (1.5kW) peak pulse power rating per the 10/1000µs waveform gives it the energy capacity for industrial surge events — motor drives, power supplies, and heavy equipment I/O lines are typical deployment points. The 274V clamping voltage at 5.5A peak pulse current sets the upper limit the downstream circuitry must survive. ## Obsolete – sourcing window is closing onsemi lists the 1.5KE200AG as Obsolete. No official successor or cross-reference is published by the manufacturer. For a BOM line that still calls out this exact order code, the practical path is to secure remaining distributor stock or evaluate a parametric equivalent from the same 1.5KE family — the 1.5KE200A (without the G suffix) or the 1.5KE200CA bidirectional variant share the same DO-201AD package and voltage ratings. Confirm the date code and lot traceability before committing to any lot found on the open market. ## DO-201AD axial – through-hole assembly fit The DO-201AD axial package is a through-hole form factor that sits well in high-reliability, high-temperature environments — the -65°C to 175°C junction temperature range supports industrial and automotive underhood use. The axial leads require manual or wave-solder assembly; no MSL concern since the part is not moisture-sensitive plastic. For a rework lab tech, the body diameter and lead spacing match standard axial-lead insertion tooling.","metaTitle":"1.5KE200AG Zener TVS Diode – onsemi Mosorb™ 1.5kW, Obsolete","metaDescription":"onsemi 1.5KE200AG Zener TVS diode, Mosorb™ series, 1.5kW peak pulse power, 171V 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":"Bulk","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)":"190V","Voltage - Clamping (Max) @ Ipp":"274V","Voltage - Reverse Standoff (Typ)":"171V","Current - Peak Pulse (10/1000µs)":"5.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/717ad1fc0ab391931f54c66e75e89e87.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I source the 1.5KE200AG if it is obsolete?","answer":"The 1.5KE200AG is marked Obsolete by onsemi, so fresh production is not available.
