No official successor or second-source order code is recorded in the lifecycle data. Qualifying an alternate TVS with similar standoff and clamping characteristics is recommended to avoid sole-source exposure on the protection rail. ## Through-hole axial package and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE82-/54 mounts through-hole — suited for point-to-point wiring or PCB layouts with plated through-holes. The 1500W peak pulse rating assumes a 10/1000µs waveform at 25°C ambient; derate above 25°C per the manufacturer's power-temperature curve. No power line protection feature is included — this is a standalone transient suppressor, not a filtered protector.","metaTitle":"Vishay 1.5KE82-E3/54 TransZorb TVS, 1500W, 66.4V Standoff","metaDescription":"Obsolete Vishay 1.5KE82-E3/54 TransZorb Zener TVS diode, 1500W peak pulse, 66.4V standoff, DO-201AA axial.","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":"Tape & Reel (TR)","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":"1.5KE82","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"73.8V","Voltage - Clamping (Max) @ Ipp":"118V","Voltage - Reverse Standoff (Typ)":"66.4V","Current - Peak Pulse (10/1000µs)":"12.7A"}},"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/1.5KE82-E3-54","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/1.5KE82-E3-54 when reusing this data.
