The DO-201AA (DO-27) axial leaded package suits through-hole assembly on boards that see vibration or thermal cycling — the leads absorb mechanical stress the way a surface-mount joint cannot. ## AEC-Q101 qualification and automotive deployment This part carries AEC-Q101 automotive qualification, meaning it has passed the stress tests (temperature cycling, high-temperature reverse bias, ESD) required for Tier-1 automotive ECU programs. The TransZorb series is Vishay's branded TVS family, optimized for repetitive surge clamping in 12 V and 24 V vehicle electrical systems. With a 14.4 V minimum breakdown voltage, the 1.5KE16HE3/54 triggers before the 23.5 V clamping ceiling, protecting downstream silicon from load-dump and inductive-load transients. The 1500 W rating at 10/1000 µs gives enough energy headroom for alternator field-decay events common in heavy truck and off-highway gear. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE16HE3/54 as obsolete. The part remains usable for existing BOM positions that cannot spin a board for a different package. For a new design, a functionally equivalent TVS in the same DO-201 package with matching 12.9 V standoff and 1500 W rating would require a board-level qualification re-run. The AEC-Q101 traceability on this lot means the parts carry the same reliability screening the original OEM spec demanded.","metaTitle":"Vishay 1.5KE16HE3/54 TVS Diode, 1500W, 12.9V Standoff","metaDescription":"Obsolete Vishay 1.5KE16HE3/54 unidirectional TVS diode, 1500W peak pulse, 12.9V 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":"Tape & Reel (TR)","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/1.5KE16HE3-54","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/1.5KE16HE3-54 when reusing this data.
