Sourcing now runs through independent surplus and broker channels; quantities are confirmed lot-specific at RFQ time. ## Clamp voltage and pulse handling for 6V rail protection With a 6.05V reverse standoff voltage, it sits across a 5V or 6V DC rail and stays transparent until a transient drives it into avalanche at 6.75V minimum breakdown. The clamp voltage peaks at 11.7V at the full 128A peak pulse current — this is the voltage the downstream circuitry must survive without latch-up or oxide rupture. ## Through-hole axial package and temperature range The wide Tj envelope suits it for environments where ambient heat and transient energy stack: industrial PSU secondary-side clamping, telecom line cards, and automotive auxiliary rails that see under-hood soak temperatures. ## Sourcing this obsolete TVS for your BOM line Because Vishay has discontinued the 1.5KE7.5-/54, no new factory orders are accepted. Our desk sources this part through independent surplus inventory — each reel is traceable and inspected for authenticity before shipment. Submit an RFQ for your target quantity; we confirm availability, date code range, and pricing per lot at quote time.","metaTitle":"1.5KE7.5-E3/54 Vishay TransZorb TVS, 1500W, 6.05V Standoff","metaDescription":"Obsolete Vishay 1.5KE7.5-E3/54 TransZorb TVS diode, 1500W peak pulse power, 6.05V standoff, 11.7V 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":"1.5KE7.5","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"6.75V","Voltage - Clamping (Max) @ Ipp":"11.7V","Voltage - Reverse Standoff (Typ)":"6.05V","Current - Peak Pulse (10/1000µs)":"128A"}},"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 can I order the 1.5KE7.5-/54 or check stock?","answer":"Submit an RFQ for the 1.5KE7.5-/54."},{"question":"What are the key clamping specs for the 1.5KE7.5-/54?","answer":"6.05V reverse standoff, 6.75V minimum breakdown, 11.7V maximum clamp at 128A peak pulse current (10/1000µs)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE7.5-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/1.5KE7.5-E3-54 when reusing this data.
