The pair shares the cathode, so the two anodes are independent — useful for OR-ing power rails, clamping, or steering logic signals where you need two Schottky barriers in one footprint. ## Leakage and forward drop — the trade-off Reverse leakage is specified at 100 nA maximum when the diode is biased at 50 V reverse. ## Package and storage note That means it arrives in a tube or bag, not on a reel for automated pick-and-place. If your line expects reels, you will need to hand-place or transfer to a carrier. The SOT-23-3 footprint is standard and matches the BAS70-05 common-cathode pair from other suppliers.","metaTitle":"BAS70-05B5003 Infineon Schottky Diode, 70 V, 70 mA, AEC-Q101","metaDescription":"Infineon BAS70-05B5003 Schottky diode, 70 V reverse voltage, 70 mA average rectified current, AEC-Q101 qualified, common-cathode pair in SOT-23 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Grade":"Automotive","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"-","Packaging":"Bulk","Technology":"Schottky","Part Status":"Active","Manufacturer":"Infineon Technologies","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Base Product Number":"BAS70","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"PG-SOT23-3-3","Current - Reverse Leakage @ Vr":"100 nA @ 50 V","Voltage - DC Reverse (Vr) (Max)":"70 V","Operating Temperature - Junction":"150°C","Voltage - Forward (Vf) (Max) @ If":"1 V @ 15 mA","Current - Average Rectified (Io) (per Diode)":"70mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dcbfe13fac2f72abdc51427ff9f52c64.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAS70-05B5003/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between BAS70-05B5003 and BAS70-05?","answer":"The BAS70-05 is the base part number for a common-cathode Schottky pair in SOT-23. The BAS70-05B5003 is a specific Infineon ordering variant that includes the Automotive grade and AEC-Q101 qualification. The electrical specs (70 V, 70 mA, 1 Vf) are the same; the difference is the qualification level and the packaging option (Bulk vs. Tape & Reel)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BAS70-05B5003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BAS70-05B5003 when reusing this data.
