Automotive Zener bidirectional TVS diode, 1.5SMCJ48CA-AU_R1_000A1, 48V reverse standoff, 77.4V clamping max, 19.4A peak pulse, 1.5kW, AEC-Q101, SMC/DO-214AB surface mount.","salesMarkdown":"## What the 48V standoff and clamping ceiling mean for the rail The 1.5SMCJ48CA-AU_R1_000A1: That 77.4V ceiling is what the protected IC sees — pick this part when the downstream silicon has a rated abs-max below that level and above 48V nominal. Bidirectional — it clamps both polarities without a polarity mark on the package. This matters on floating 48V rails and any circuit where the ground reference can ring positive during a surge event. ## AEC-Q101 grade — what it changes vs a commercial TVS AEC-Q101 qualification means the part passed the automotive stress suite: humidity, temperature cycling, and surge lifetime testing under datasheet conditions. For an ECU input or an ECU power rail clamp, this is the minimum bar — a commercial-grade TVS in the same SMC package may not hold the same margin over the automotive temperature range. Junction temperature rating is -55°C to 150°C — the top of the range covers the under-hood ambient band with margin. An engine-bay node seeing 125°C ambient still has 25°C of junction rise budget before the spec ceiling. ## SMC/DO-214AB footprint and the 1.5kW rating Board layout must keep the cathode pad area close to the package thermal spec in the datasheet drawing — a reduced pad suppresses the peak pulse capability below the 1.5 kW rating.","metaTitle":"1.5SMCJ48CA-AU_R1_000A1 Zener TVS Diode, 48V, 1.5kW","metaDescription":"Panjit 1.5SMCJ48CA-AU_R1_000A1 — AEC-Q101 bidirectional TVS Zener, 48V standoff, 77.4V clamping, 1.5kW peak pulse, SMC/DO-214AB 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","Grade":"Automotive","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"-","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","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","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Voltage - Breakdown (Min)":"53.3V","Voltage - Clamping (Max) @ Ipp":"77.4V","Voltage - Reverse Standoff (Typ)":"48V","Current - Peak Pulse (10/1000µs)":"19.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I source 1.5SMCJ48CA-AU_R1_000A1 and get a quote?","answer":"Quoted to order through independent distribution against your BOM quantity."},{"question":"What compliance documentation does Panjit provide for this part?","answer":"The part is AEC-Q101 qualified, which is the automotive stress-grade compliance for discrete semiconductors.
