For a BOM line that calls out this 1.5 kW TransZorb, the procurement path runs through independent surplus and broker channels, not the factory. Availability is lot-specific and confirmed at RFQ time. ## Protection ratings that decide the fit Reverse standoff voltage is 171 V — the TVS stays off below this rail voltage. Breakdown triggers at 190 V minimum, clamping the transient to 274 V maximum at the 5.5 A peak pulse current (10/1000 µs waveform). The 274 V clamp means a 400 V rated downstream capacitor sees a safe voltage during the event. Single unidirectional channel — polarity matters on the board. The anode-to-ground orientation must match the DC rail being protected. ## Package and rework reality DO-201AA (DO-27) axial-lead, through-hole — a hand-solder-friendly package. The leads are stout enough to survive a rework cycle without pad lift, and the body orientation (cathode band) is clearly marked on the part.","metaTitle":"Vishay 1.5KE200A/54 TransZorb TVS, 1.5kW, 274V Clamp","metaDescription":"Vishay 1.5KE200A/54 TransZorb Zener TVS diode, 1500W peak pulse, 274V clamping, DO-201AA axial.","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":"1.5KE200","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"190V","Voltage - Clamping (Max) @ Ipp":"274V","Voltage - Reverse Standoff (Typ)":"171V","Current - Peak Pulse (10/1000µs)":"5.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE200A-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/1.5KE200A-54 when reusing this data.
