The 1500 W peak pulse rating at the 10/1000 µs test waveform is the standard industrial surge rating; for shorter pulses (8/20 µs) the peak power capability is higher, but the clamping voltage at the actual surge current is the parameter that determines whether the protected load stays within its safe operating area. General-purpose application classification means it is not optimized for power-line protection (no internal power-line protection circuitry) — it is intended for signal, data, and DC rail transient suppression where the standoff voltage matches the normal operating voltage.","metaTitle":"Vishay 1.5KE56C-E3/54 TransZorb TVS, 1500W, 45.4V, Obsolete","metaDescription":"Obsolete Vishay 1.5KE56C-E3/54 bidirectional Zener TVS diode, 1500W peak pulse power, 45.4V standoff, DO-201AA.","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":"1.5KE56","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"50.4V","Voltage - Clamping (Max) @ Ipp":"80.5V","Voltage - Reverse Standoff (Typ)":"45.4V","Current - Peak Pulse (10/1000µs)":"18.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1.5KE56C-/54 come in?","answer":"It is supplied in a DO-201AA (DO-27) axial-lead through-hole package, on tape and reel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE56C-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/1.5KE56C-E3-54 when reusing this data.
