Its 70 V DC reverse voltage and 70 mA average rectified current define the operating envelope for low-power clamping, freewheeling, and OR-ing diodes on 12 V and 24 V vehicle rails. The 1.5 pF junction capacitance at 0 V keeps signal edges clean in high-speed switching or RF detector circuits, while the 0.1 µA reverse leakage at 50 V ensures minimal quiescent drain in always-on modules. ## AEC-Q101 grade — qualification scope The Automotive, AEC-Q101 series designation means this part has passed the stress tests required for automotive-grade discrete semiconductors: temperature cycling, HTRB, H3TRB, and ESD robustness per the AEC-Q101 rev. The 150°C maximum junction temperature supports under-hood and engine-bay thermal profiles. Active lifecycle status confirms no end-of-life or last-time-buy notice is in effect, so the part is available for ongoing production builds without a forced redesign. ## Package and footprint Supplied in the PG-SOT23-3-3 package (TO-236-3 / SC-59 / SOT-23-3 footprint). The three-pin SOT-23 lands on a standard 0.95 mm pitch layout shared across the BAS70 family, making it a drop-in for existing Schottky footprints on automotive PCBs. Surface-mount assembly with standard reflow profiles; no special pad geometry required.","metaTitle":"BAS70B5003 Schottky Diode, 70 V, 70 mA, AEC-Q101, SOT-23-3","metaDescription":"Infineon BAS70B5003 automotive Schottky diode, 70 V reverse voltage, 70 mA average rectified current, 1.5 pF capacitance, AEC-Q101 qualified.","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":"Is BAS70B5003 AEC-Q101 certified?","answer":"Yes, the series is listed as Automotive, AEC-Q101."},{"question":"What is the closest pin-compatible alternative to BAS70B5003?","answer":"The BAS70 family shares the same SOT-23-3 footprint and similar 70 V / 70 mA ratings.
