Breakdown kicks in at 122 V minimum, which means the device guarantees it is OFF below that threshold. That 67 V differential between standoff and clamping ceiling is the voltage margin the downstream IC sees before the TVS turns hard on — it is the defining spec for how much stress survives the clamp. This is not a continuous dissipation rating — it is a single-event, short-duration capability. Board-level layout matters here: the SMC package thermal path runs through the cathode pad to the board copper, so a modest landing pad and thin dielectric under the part will push junction temperature above the 150 °C ceiling on repeated events. The 150 °C maximum junction rating is well above the 125 °C many consumer-grade TVS parts cap out at. This headroom matters in sealed enclosures, multi-board stacks where adjacent components dump heat onto the plane, or outdoor equipment where solar load adds to the thermal budget. At the cold end, -55 °C qualification covers cold-start transients and outdoor winter deployments without derating concerns — the clamping voltage actually tightens at low temperature, so the protection level improves, not degrades. ## SMC package and surface-mount assembly context The DO-214AB (SMC) is a dominant package for 1500 W TVS parts — the cathode bar and wide body give the thermal pad area needed for single-pulse energy absorption. Tape-and-reel packaging (TR) is standard; cut tape (CT) is also listed, which suits prototype quantities without committing to a full reel. Surface-mount reflow profile follows the standard lead-free schedule — no special thermal excursion is required compared to other SMC parts.","metaTitle":"1.5SMCJ110A_R1_00001 TVS Diode, 110V Standoff, 177V Clamp","metaDescription":"Panjit 1.5SMCJ110A_R1_00001 unidirectional TVS diode, 110V standoff, 177V clamp at 8.4A peak pulse, 1500W peak power, DO-214AB SMC surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International Inc.","Type":"Zener","Series":"1.5SMCJ","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Active","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","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)":"122V","Voltage - Clamping (Max) @ Ipp":"177V","Voltage - Reverse Standoff (Typ)":"110V","Current - Peak Pulse (10/1000µs)":"8.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a271c765b4bf7e62ca251a7791548580.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative in the 1.5SMCJ series?","answer":"The 1.5SMCJ series is pin-compatible across standoff voltage variants — any part sharing the same DO-214AB SMC footprint and 110 V family can be evaluated as a drop-in, but the exact breakdown and clamping characteristics shift with the standoff voltage selected.
