It is qualified to AEC-Q101, making it suitable for automotive and other high-reliability environments where the part must meet the stress and lifetime requirements of the automotive electronics council. Each diode is rated for a maximum reverse voltage of 70 V and an average rectified current of 70 mA (DC). Forward voltage is specified at 1 V maximum when carrying 15 mA. Reverse leakage is 100 nA maximum at 50 V reverse bias. The series-connected configuration is useful for applications requiring two Schottky diodes in series — for example, in clamping networks, steering diodes, or as a voltage-doubling stage — where a single SOT-23 footprint replaces two discrete diodes. ## 70 V blocking, 70 mA forward — what the ratings mean The 70 V reverse voltage rating sets the maximum DC or repetitive peak reverse voltage the diode can block. The 70 mA average rectified current per diode is the DC load limit. Forward voltage of 1 V at 15 mA is typical for a small-signal Schottky — the low Vf compared to a PN-junction diode reduces conduction loss in low-current rectification or OR-ing applications. The 100 nA leakage at 50 V is low enough for battery-powered or high-impedance sense circuits where leakage current would otherwise shift bias points. Operating junction temperature is rated to 150 °C, which aligns with under-hood automotive ambient temperatures when derated for self-heating.","metaTitle":"Infineon BAS70-04B5000 Schottky Diode, 70 V, 70 mA, AEC-Q101","metaDescription":"Infineon BAS70-04B5000 automotive Schottky diode, 70 V reverse voltage, 70 mA average rectified current, 1 V forward drop at 15 mA, 100 nA leakage at 50 V.","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","Diode Configuration":"1 Pair Series Connection","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","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dcbfe13fac2f72abdc51427ff9f52c64.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BAS70-04B5000 AEC-Q101 qualified?","answer":"Yes, the BAS70-04B5000 is listed under the Automotive, AEC-Q101 series.
