Power line protection is listed as No — this part is not characterized for direct placement across a mains-input power rail without additional insulation and spacing per applicable safety standards. ## Package, mounting, and telecom deployment context The DO-214AB (SMC) is a standard surface-mount package with a wide, flat body — the cathode bar is the exposed pad area and should be soldered to a generous land pad for thermal relief. Supplied on Tape & Reel for automated placement, the part is fully compatible with standard lead-free reflow profiles up to the paste and board thermal budget of a typical telecom switch or base-station power-supply board. The Telecom application designation reflects its use on the secondary side of a DC power bus feeding radio equipment — protection of control logic and communication ASICs from inductive kickback on long cable runs.","metaTitle":"1.5SMC82AH TVS Diode, 1.5kW Peak Pulse, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC82AH unidirectional Zener TVS diode, 70.1V standoff, 113V clamping, 1.5 kW peak pulse, AEC-Q101, DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Grade":"Automotive","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"Telecom","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC82","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"77.9V","Voltage - Clamping (Max) @ Ipp":"113V","Voltage - Reverse Standoff (Typ)":"70.1V","Current - Peak Pulse (10/1000µs)":"13.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2104","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9c9b573e4c81d1eb42c6ffefbf34e6d8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC82AH/alternatives.json"},"ai":{"faq":[{"question":"Where can I source the 1.5SMC82AH and what are the typical lead times?","answer":"The 1.5SMC82AH is quoted to order through independent distribution against an RFQ; availability and lead times are confirmed at quote time rather than from a live stock figure."},{"question":"What compliance documentation does Taiwan Semiconductor provide for the 1.5SMC82AH?","answer":"The part is AEC-Q101 qualified, which is the automotive discrete-semiconductor reliability stress standard — it covers temperature cycling, humidity bias, and surge testing at the component level.
