Its low forward voltage — 1 V maximum at 15 mA — and junction capacitance of 1.5 pF at 0 V make it suited for high-speed switching, reverse-polarity protection, and clamping in 12 V and 24 V automotive electronics, industrial controls, and general-purpose signal conditioning. The 70 V reverse voltage gives comfortable headroom over a 12 V rail, and the sub-100 nA leakage at 50 V keeps power loss negligible in battery-powered circuits. ## AEC-Q101 — why it matters for the BOM The BAS70B5000 carries the Automotive, AEC-Q101 series designation, meaning it has passed the stress qualification tests (temperature cycling, HTRB, H3TRB, etc.) required for production automotive electronics. For a BOM line going into an ECU, sensor module, or under-hood assembly, this qualification removes the need for a separate qualification run or waiver. The 150 °C maximum junction temperature supports operation in under-hood ambient conditions where the local temperature can reach 105 °C or higher. Infineon lists the BAS70B5000 with an Active product status. ## Package and footprint — SOT-23-3 The BAS70B5000 is supplied in the PG-SOT23-3-3 package, a standard three-lead SOT-23 footprint shared with many small-signal diodes and transistors. The surface-mount body suits automated pick-and-place and reflow assembly.","metaTitle":"Infineon BAS70B5000 Schottky Diode, 70 V, 70 mA, AEC-Q101","metaDescription":"Infineon BAS70B5000 small-signal Schottky diode, 70 V reverse voltage, 70 mA average current, 1.5 pF capacitance, AEC-Q101 qualified in SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"Automotive, AEC-Q101","Package":"Bulk","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","lifecycle_stage":"eol_hot","Capacitance @ Vr, F":"1.5pF @ 0V, 1MHz","Supplier Device Package":"PG-SOT23-3-3","Current - Reverse Leakage @ Vr":"0.1 µA @ 50 V","Voltage - DC Reverse (Vr) (Max)":"70 V","Current - Average Rectified (Io)":"70mA","Operating Temperature - Junction":"150°C","Voltage - Forward (Vf) (Max) @ If":"1 V @ 15 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dcbfe13fac2f72abdc51427ff9f52c64.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to BAS70B5000?","answer":"This part is a standard SOT-23-3 Schottky diode.
