Breakdown starts at 11.4V minimum, so a 12V bus that sags to 11.5V during a transient is still within the safe window; the device does not conduct until the avalanche threshold is crossed.","metaTitle":"Vishay 1.5KE12A-E3/54 TransZorb TVS, 1500W, 10.2V Standoff","metaDescription":"Vishay 1.5KE12A-E3/54 TransZorb Zener TVS diode, 1500W peak pulse, 10.2V reverse standoff, 89.8A Ipp. Active lifecycle, through-hole DO-201AA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE12","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"11.4V","Voltage - Clamping (Max) @ Ipp":"16.7V","Voltage - Reverse Standoff (Typ)":"10.2V","Current - Peak Pulse (10/1000µs)":"89.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3246","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE12A-E3%2F54/alternatives.json"},"ai":{"faq":[{"question":"What package does the 1.5KE12A-/54 come in?","answer":"It is supplied in a DO-201AA (DO-27) axial through-hole package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE12A-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/1.5KE12A-E3-54 when reusing this data.
