The 23.1 A peak pulse current rating at the standard 10/1000 µs test waveform gives a direct read on the surge it can absorb — a 1500 W device at 64.8 V clamping voltage works out to that current by design. ## Obsolete — sourcing through independent channels Available through independent distribution as new-old-stock or surplus inventory. For a BOM that already carries this part number, the supply posture is quoted-to-order through the broker channel — the buyer confirms the quantity and we locate the material from franchised excess or independent surplus. ## Bidirectional, axial-leaded, wide-temp Rated for junction temperatures from -55°C to 175°C, the part covers industrial and military ambient ranges — the 175°C TJ max gives headroom in sealed enclosures or near hot components.","metaTitle":"Vishay 1.5KE47CA/54 TVS Diode, 1500W, 40.2V Standoff","metaDescription":"Vishay TransZorb® 1.5KE47CA/54 bidirectional TVS diode, 1500W peak pulse power, 40.2V reverse 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","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":"1.5KE47","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1.5KE47CA/54 unidirectional or bidirectional?","answer":"Bidirectional — a single device clamps transients of either polarity, suitable for AC or bipolar DC protection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE47CA-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/1.5KE47CA-54 when reusing this data.
