The ±5% tolerance on the zener voltage means the regulation point sits between 86.45 V and 95.55 V — a spread that matters when the downstream circuit has a tight overvoltage trip threshold. ## Temperature range and derating Operating from -65°C to 150°C, this diode covers the full automotive under-hood and military temperature envelope. At 150°C junction temperature the 1 W power rating must be derated per the standard SMA thermal resistance curve — the copper pad area under the cathode tab directly sets the junction-to-ambient thermal path. The AEC-Q101 qualification means this part has passed the automotive-grade stress tests: temperature cycling, high-temperature reverse bias, and humidity. For a BOM that needs a 91 V clamp in an ECU, ABS module, or battery-management system, this qualification removes the need for a separate qualification run on a commercial-grade zener.","metaTitle":"SML4763AHE3_A/I 91V Zener Diode, 1W, DO-214AC, AEC-Q101","metaDescription":"Vishay SML4763AHE3_A/I 91V zener diode, 1W power rating, ±5% tolerance, DO-214AC SMA package, AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±5%","Power - Max":"1 W","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","lifecycle_stage":"eol_hot","Impedance (Max) (Zzt)":"250 Ohms","Operating Temperature":"-65°C ~ 150°C","Supplier Device Package":"DO-214AC (SMA)","Voltage - Zener (Nom) (Vz)":"91 V","Current - Reverse Leakage @ Vr":"5 µA @ 69.2 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.58","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.58000","currency":"USD"},{"qty":10,"price":"$0.49700","currency":"USD"},{"qty":100,"price":"$0.37100","currency":"USD"},{"qty":500,"price":"$0.29150","currency":"USD"},{"qty":1000,"price":"$0.22525","currency":"USD"},{"qty":2000,"price":"$0.20625","currency":"USD"},{"qty":7500,"price":"$0.20625","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a17c7484b951152c402634a7e2b2a28a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SML4763AHE3_A/I AEC-Q101 qualified?","answer":"Yes, the SML4763AHE3_A/I is part of Vishay's Automotive AEC-Q101 series, meaning it has passed the automotive-grade qualification tests for stress, reliability, and temperature extremes."},{"question":"What is the reverse leakage specification for SML4763AHE3_A/I?","answer":"Reverse leakage current is 5 µA maximum at 69.2 V reverse voltage.
