For a 48 V nominal rail, this TVS provides a clamp that stays below the downstream device's absolute maximum rating. The 1.5KE package suffix indicates the body size; the leads are tin-plated copper for solderability. For new layouts, the axial lead spacing and hole diameter follow the DO-201AA land pattern — no special thermal pad is required, but the copper trace width to the leads should handle the 19.5 A peak pulse current without fusing.","metaTitle":"Vishay 1.5KE56CAHE3/51 TransZorb TVS, 1500W, 47.8V Standoff","metaDescription":"Obsolete Vishay 1.5KE56CAHE3/51 bidirectional TVS diode, 1500W peak pulse, AEC-Q101, 47.8V standoff.","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","Grade":"Automotive","Series":"TransZorb®","Packaging":"Bulk","Part Status":"Obsolete","Applications":"-","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-201AA, DO-27, Axial","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE56","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"53.2V","Voltage - Clamping (Max) @ Ipp":"77V","Voltage - Reverse Standoff (Typ)":"47.8V","Current - Peak Pulse (10/1000µs)":"19.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5346","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6470e7c23af28f3f376ae45aee8e9ef.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE56CAHE3%2F51/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE56CAHE3-51","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/1.5KE56CAHE3-51 when reusing this data.
