That 77V clamping ceiling is the stress the downstream circuit sees even during a genuine surge event; sizing the TVS means confirming the clamping voltage stays below the absolute-maximum input rating of whatever transceiver or DSP sits behind it. Telecom front-end protection typically faces 500V-1kV test surges per IEC 61000-4-5; the 1.5kW rating at the standard 10/1000µs test wave places this device in the medium-energy class, suited for line-card inputs and DSL edge protection rather than full-ac-line entry. ## Wide junction temperature range for outdoor and high-density rack deployment The DO-214AB SMC package is the industry-standard surface-mount outline for TVS diodes — the cathode bar is the larger die-attached pad, and the recommended land pattern uses a thermal pad under the cathode to conduct heat into the board copper. The base product number 1.5SMC56 anchors the 56V standoff grade within the 1.5SMC series — other voltage grades within the same package are pin-compatible and share the same tape-and-reel packaging, so the sourcing base is broad.","metaTitle":"1.5SMC56CA V7G TVS Diode, 47.8V standoff, 77V clamp","metaDescription":"Taiwan Semiconductor 1.5SMC56CA V7G bidirectional TVS diode, 47.8V reverse standoff, 77V clamping, 1500W peak pulse, DO-214AB SMC surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"Telecom","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC56","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"53.2V","Voltage - Clamping (Max) @ Ipp":"77V","Voltage - Reverse Standoff (Typ)":"47.8V","Current - Peak Pulse (10/1000µs)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2922","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC56CA%20V7G/alternatives.json"},"ai":{"faq":[{"question":"Who supplies 1.5SMC56CA V7G and how is it quoted for volume purchases?","answer":"Sourced through independent distribution as a Taiwan Semiconductor Corporation branded line.

Other standoff voltages within the series (such as the 1.5SMC51CA or 1.5SMC62CA) are mechanically and electrically compatible for the same board footprint — the choice is driven by the protected rail voltage rather than a form-factor constraint.
