The DO-201AA axial package (DO-27 equivalent) is through-hole mounted, suited for point-of-entry protection on PCB edge connectors or bulkhead feed-throughs. ## Sourcing an obsolete AEC-Q101 TVS Vishay lists this part as obsolete. The AEC-Q101 qualification and TransZorb construction remain the same across the 1.5KE family, so a parametric cross-reference within that family is the practical path for a BOM replacement.","metaTitle":"1.5KE150AHE3/51 Vishay TVS, 1.5kW, 128V Standoff, DO-201","metaDescription":"Obsolete Vishay 1.5KE150AHE3/51 TVS diode, 1500W peak pulse, 128V reverse standoff, AEC-Q101 qualified.","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":"Automotive, AEC-Q101, TransZorb®","Package":"Bulk","Applications":"Automotive","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":"1.5KE150","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"143V","Voltage - Clamping (Max) @ Ipp":"207V","Voltage - Reverse Standoff (Typ)":"128V","Current - Peak Pulse (10/1000µs)":"7.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5346","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55e3e40e24fd2c3f96443c3e231bf459.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE150AHE3%2F51/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 1.5KE150AHE3/51 and get a price?","answer":"Current pricing and available quantities are confirmed at quote time — submit an RFQ for your BOM quantity and target delivery window."},{"question":"What is the closest pin-compatible alternative to the 1.5KE150AHE3/51?","answer":"The 1.5KE series shares the same DO-201AA footprint and TransZorb construction — a parametric cross-reference within that family (same standoff voltage, same pulse power rating) is the practical replacement path.
