Peak pulse current is 10.9 A for the 10/1000 µs double-exponential waveform. The 1500 W rating is the product of clamp voltage and peak current at that waveform; a shorter pulse (8/20 µs) will sustain a higher peak current, but the 10/1000 µs figure is the standard comparison point for mains-borne transients. The DO-201AA axial-lead package (also known as DO-27) is a through-hole form factor. The junction temperature range spans -55°C to +175°C, covering military and industrial thermal environments without derating at the high end. ## Sourcing an obsolete TVS — what to expect Vishay lists the 1.5KE100CA/54 as obsolete. No official successor order code is recorded in the lifecycle data. Replacement sourcing relies on surplus or broker inventory — each lot is verified for authenticity and traceability before shipment. A functionally equivalent bidirectional TVS in the same package (DO-201AA) with a standoff voltage of 85.5 V and a 1500 W peak pulse rating can be sourced as a cross-reference, but pin-compatibility is package-defined — the axial leads are identical across the form factor. The replacement must match the clamp voltage and breakdown window to preserve the protection level.","metaTitle":"Vishay 1.5KE100CA/54 TransZorb TVS, 1500W, 85.5V Standoff","metaDescription":"Obsolete Vishay 1.5KE100CA/54 bidirectional TVS diode, 1500W peak pulse, 85.5V 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":"1.5KE100","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Voltage - Breakdown (Min)":"95V","Voltage - Clamping (Max) @ Ipp":"137V","Voltage - Reverse Standoff (Typ)":"85.5V","Current - Peak Pulse (10/1000µs)":"10.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 1.5KE100CA/54?","answer":"The 1.5KE100CA/54 is obsolete and sourced through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE100CA-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/1.5KE100CA-54 when reusing this data.
