Zener TVS, AEC-Q101 automotive, 54V standoff, 87.1V clamping, 17.2A, 1500W peak pulse, DO-214AB SMC, surface mount, 1.5SMCJ54A-AU_R1_000A1.","salesMarkdown":"## Clamping voltage — what 87.1 V means for the downstream load The 1.5SMCJ54A-AU_R1_000A1: At 87.1 V maximum clamping voltage with a 17.2 A peak pulse (10/1000 µs surge waveform), the TVS diverts surge energy away from whatever circuit sits behind it — the lower the clamping voltage relative to the downstream IC abs-max, the more headroom survives the event. For a 48 V automotive rail this part clamps at 87.1 V, giving roughly 39 V of margin above the standoff rail before the diode turns on. ## AEC-Q101 — the automotive qualification that matters for under-hood designs The AEC-Q101 qualification puts this part through temperature cycling, humidity bias, and surge life testing that a commercial TVS skips — an engine-bay ECU that sees -40 °C at cold crank and 150 °C at the junction under full load needs exactly that margin. ## Standoff voltage — the selection axis that sets the rail ceiling 54 V typical reverse standoff is the maximum reverse bias the diode tolerates continuously without conducting — the circuit rail must stay at or below 54 V during normal operation for this part to be the right fit. Any transient that exceeds 54 V triggers the clamping action, pulling the overvoltage down to the 87.1 V ceiling while the diode handles the 17.2 A surge current. 60 V minimum breakdown voltage is the point at which the Zener conduction mechanism formally begins; in practice the clamping knee is softer and the 87.1 V maximum clamping spec is what the downstream circuit must survive. ## SMC package and independent sourcing The DO-214AB SMC is the standard large-current TVS footprint — the cathode pad under the package carries the thermal path to the board copper. Both Tape & Reel and Cut Tape packaging are listed, covering high-volume placement and low-volume rework alike.","metaTitle":"1.5SMCJ54A-AU_R1_000A1 Panjit 1.5SMCJ54A-AU 54V TVS Diode","metaDescription":"Panjit 1.5SMCJ54A-AU unidirectional Zener TVS, 54V standoff, 87.1V clamping, 1.5kW peak pulse, AEC-Q101 automotive, 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)":"60V","Voltage - Clamping (Max) @ Ipp":"87.1V","Voltage - Reverse Standoff (Typ)":"54V","Current - Peak Pulse (10/1000µs)":"17.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the 1.5SMCJ54A-AU_R1_000A1 series and qualification level?","answer":"It is listed in the Automotive AEC-Q101 series — a Zener unidirectional TVS qualified for automotive deployment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ54A-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/1.5SMCJ54A-AU_R1_000A1 when reusing this data.
