The single bidirectional channel handles positive and negative transients symmetrically, eliminating the need for two back-to-back unidirectional devices on a bipolar rail. ## Package and board integration Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE47CAHE3/51 is a through-hole device. The axial body and 0.042-inch diameter leads suit point-to-point wiring, terminal block termination, or PCB through-hole mounting where the lead bend radius is controlled to avoid stress cracking the glass passivation. The bulk packaging (51 pieces per bag) is typical for low-volume production runs, repair stock, or engineering samples. No reel or tape-and-reel option is listed — the part ships loose in anti-static tubes or bags per the bulk code.","metaTitle":"Vishay 1.5KE47CAHE3/51 TVS, 1.5kW, 40.2V Standoff, DO-201","metaDescription":"Obsolete Vishay 1.5KE47CAHE3/51 bidirectional TVS diode, 1500W peak pulse, 40.2V standoff, AEC-Q101.","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":"Automotive, AEC-Q101, TransZorb®","Package":"Bulk","Applications":"Automotive","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":"1.5KE47","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"44.7V","Voltage - Clamping (Max) @ Ipp":"64.8V","Voltage - Reverse Standoff (Typ)":"40.2V","Current - Peak Pulse (10/1000µs)":"23.1A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5346","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55e3e40e24fd2c3f96443c3e231bf459.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 1.5KE47CAHE3/51 and get a price?","answer":"No stock-holding claim is made; the channel is surplus and excess inventory."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE47CAHE3-51","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/1.5KE47CAHE3-51 when reusing this data.
