Breakdown occurs at 77.9 V minimum, so the protection triggers before the bus reaches 78 V. This is a unidirectional device (single channel) — the cathode band marks the protected side; the anode connects to ground. ## Package and temperature range for through-hole designs Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE82A/54 mounts through-hole. The axial lead form factor is a direct-fit replacement for legacy through-hole TVS sockets — no board respin required if the existing layout uses a DO-201 footprint.","metaTitle":"Vishay 1.5KE82A/54 TransZorb TVS, 1500W, 113V Clamp","metaDescription":"Vishay 1.5KE82A/54 TransZorb Zener TVS diode, 1500W peak pulse, 70.1V standoff, 113V 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":"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)":"77.9V","Voltage - Clamping (Max) @ Ipp":"113V","Voltage - Reverse Standoff (Typ)":"70.1V","Current - Peak Pulse (10/1000µs)":"13.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How do I get pricing and availability for 1.5KE82A/54?","answer":"Submit an RFQ against your BOM quantity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE82A-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/1.5KE82A-54 when reusing this data.
