The minimum breakdown of 7.79 V sits above the 7.02 V standoff, giving the circuit normal operating headroom — the device stays off and leakage is negligible until the transient pushes the rail past breakdown. Operating junction temperature runs to 150 °C, which handles the self-heating spike during a clamping event without derating for most panel-level deployments. ## SMC package and board-level fit The DO-214AB SMC is a standard surface-mount package with a wide copper pad under the cathode tab — thermal resistance from junction to ambient is set by the pad solder joint and board copper area, not the housing. The supplier device package is listed as SMCJ, which is the common industry designation for this footprint; confirm the landing pattern matches the datasheet land pattern for the cathode-anode spacing before committing a new layout. Tape-and-reel and cut-tape packaging suit both high-volume placement and small-batch rework — the DO-214AB is reball-ready for BGA-adjacent replacement scenarios, and the surface-mount form factor accepts standard hot-air or IR rework profiles. ## Active sourcing posture The 1.5SMC series is a long-running Littelfuse family, so second-source alternatives in the same SMCJ footprint are typically available from competing TVS suppliers if BOM hedge is a concern. Confirm the standoff and clamping specs match the legacy Littelfuse values before swapping, since TVS breakdown grading can vary between manufacturers.","metaTitle":"1.5SMC8.2A TVS Diode, 7.02V standoff, Littelfuse","metaDescription":"Littelfuse 1.5SMC8.2A unidirectional TVS diode, 1500W peak pulse, 12.1V clamping at 125.6A, DO-214AB SMC package, -55 to 150°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","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 (SMCJ)","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)":"125.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/118f1b70ec0f0941665a20e5472af60a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC8.2A/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 1.5SMC8.2A and how do I get a price?","answer":"Submit an RFQ and the sourcing desk confirms current pricing and lead time across authorized and independent channels — no stock count published, availability confirmed at quote time."},{"question":"What is the closest pin-compatible alternative to 1.5SMC8.2A?","answer":"The 1.5SMC series is Littelfuse-specific branding, but any 1500 W unidirectional TVS in the DO-214AB (SMCJ) package with a 7–8 V standoff and 12 V clamping ceiling is a candidate.
