When a transient pushes the rail above 33.3 V the Zener avalanche kicks in, clamping the peak surge to 48.4 V. That 48.4 V clamping ceiling is what the downstream IC sees — the 1.5 kW peak-pulse rating buys the headroom needed to absorb a 10/1000 µs surge without going into thermal runaway. The 31 A peak pulse figure tells you the device survives a single-event surge of that magnitude without degradation — useful for load-dump and inductive kickback events on the 12 V automotive rail. If you are protecting a sensor line that runs through the bulkhead or near the exhaust, this temperature window is the difference between a protection circuit that holds and one that thermally trips under a sustained load dump. ## DO-214AB SMC — footprint and assembly note The DO-214AB (SMC) package is the mid-range SMA/SMB footprint — larger than a SOD-123F but with better thermal dissipation than a SMA. Solder-mask defined pad recommended; the cathode band marks the polarity stripe. Supplied on Tape & Reel and Cut Tape — reel quantities suit high-volume assembly runs. Surface-mount reflow profile with standard lead-free paste works; the SMC body sits flush with the board, so thermal relief to the copper plane under the part matters more than the body height for surge-withstand margin.","metaTitle":"1.5SMCJ30A-AU_R1_000A1 Panjit 1.5SMCJ30A-AU 30V TVS Diode","metaDescription":"Panjit International 1.5SMCJ30A-AU_R1_000A1 — unidirectional Zener TVS, 30V standoff, 48.4V clamping, 31A 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":"Panjit International Inc.","Type":"Zener","Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"33.3V","Voltage - Clamping (Max) @ Ipp":"48.4V","Voltage - Reverse Standoff (Typ)":"30V","Current - Peak Pulse (10/1000µs)":"31A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ30A-AU_R1_000A1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ30A-AU_R1_000A1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMCJ30A-AU_R1_000A1 when reusing this data.
