No official successor order code is recorded in the lifecycle documentation. The part is no longer available through Vishay's franchised distribution channel for new production orders. Sourcing for this order code runs through independent surplus and excess inventory channels. Availability is lot-specific and confirmed at RFQ — the part carries no manufacturer warranty from the original factory. Buyers should verify date code, quantity, and traceability against their BOM line before committing. ## Package and mounting — axial leaded DO-201AA The through-hole package is DO-201AA, also known as DO-27, axial leaded. The 1.5KE body is the standard Vishay outline for this power class. Lead spacing and body diameter match the common 1.5KE footprint used across the industry — the PCB hole pattern and lead bend radius are the same as any 1.5KE-series bidirectional TVS in this package. Mounting is through-hole with axial leads; the part is supplied in bulk. No MSL rating applies to leaded glass-passivated devices — no bake-out or moisture sensitivity handling is required before soldering.","metaTitle":"Vishay 1.5KE350CA-E3/51 TransZorb TVS, 1.5kW, 482V Clamp","metaDescription":"Obsolete Vishay 1.5KE350CA-E3/51 bidirectional TVS diode, 1500W peak pulse, 300V standoff, 482V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Bulk","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":"1.5KE350","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"333V","Voltage - Clamping (Max) @ Ipp":"482V","Voltage - Reverse Standoff (Typ)":"300V","Current - Peak Pulse (10/1000µs)":"3.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does 1.5KE350CA-/51 use?","answer":"The package is DO-201AA, also designated DO-27, axial leaded.
