For BOM lines that still carry this part number, supply runs through independent surplus and broker channels. ## 1500W Zener TVS — what the ratings mean for the protection decision That clamping voltage is what the downstream circuitry must survive — a 12V-tolerant input stage has headroom; a 5V logic rail needs additional series resistance or a secondary clamp. The wide band also means the leakage current at the standoff voltage shifts with temperature; at 175°C the standby draw is higher than the 25°C datasheet typical. ## DO-201 axial — package and board-fit note The 1.5KE8V2A-B comes in a DO-201AA / DO-27 axial-lead package, through-hole mount, supplied in bulk. The DO-201 body is larger than the common DO-41 or SMA packages — the lead diameter and body length take up more board area and require a drilled hole with a larger pad diameter for thermal and mechanical support. Axial-lead TVS diodes are often specified in point-to-point wiring or terminal-block layouts where the leads are bent and soldered into a PCB or turret terminal. The bulk packaging means no reel or tape — each unit is handled individually, which is typical for through-hole assembly or rework stations. ## Signal-line protection — no power line rating The 1.5KE8V2A-B carries a 'Power Line Protection: No' flag, meaning it is not rated for direct AC mains or high-energy power-line transients. Its intended use is on DC signal, data, or low-voltage power buses where the energy in a 10/1000µs surge is within the 1500W peak pulse envelope. With a single unidirectional channel, this TVS protects one line per device. Bidirectional or multi-channel configurations require a different part — the 1.5KE series includes bidirectional variants, but this specific order code is unidirectional.","metaTitle":"1.5KE8V2A-B Zener TVS, 1500W, 7.02V standoff, DO-201","metaDescription":"Diodes Inc 1.5KE8V2A-B Zener TVS — obsolete. 1500W peak pulse, 7.02V standoff, 12.1V clamp, DO-201 axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diodes Incorporated","Type":"Zener","Series":"-","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE8V2","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"7.79V","Voltage - Clamping (Max) @ Ipp":"12.1V","Voltage - Reverse Standoff (Typ)":"7.02V","Current - Peak Pulse (10/1000µs)":"124A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6b9d4121cb66208511919f4a66769e1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the 1.5KE8V2A-B come in?","answer":"It is supplied in a DO-201AA / DO-27 axial-lead through-hole package, delivered in bulk (no reel or tape).
