For a 12V battery line, a load-dump pulse that exceeds the 14.4V minimum breakdown triggers conduction; the diode clamps the transient to 23.5V, absorbing the energy as heat across the junction. ## Sourcing an obsolete AEC-Q101 TVS Vishay has marked the 1.5KE16HE3/73 as obsolete. The DO-201AA axial package is a standard footprint; a functional replacement from the same 1.5KE family would require verifying the breakdown and clamping voltages match the BOM requirement.","metaTitle":"1.5KE16HE3/73 Vishay TVS Zener, 1500W, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE16HE3/73 TVS Zener diode, 1500W peak pulse, 12.9V 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":"Tape & Box (TB)","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":"1.5KE16","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"14.4V","Voltage - Clamping (Max) @ Ipp":"23.5V","Voltage - Reverse Standoff (Typ)":"12.9V","Current - Peak Pulse (10/1000µs)":"63.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE16HE3-73","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE16HE3-73 when reusing this data.
