The AEC-Q101 qualification targets it for automotive electronics — under-hood modules, body controllers, and infotainment — where the 150°C junction temperature rating handles the thermal cycling of an engine bay or cabin. The common-cathode pair is useful for OR-ing power rails, clamping inductive loads, or building a rail-to-rail protection clamp with two diodes in one package, saving board space over two single SOT-23 diodes. ## 70 V reverse voltage — what it buys you The 70 V VR(max) is the hard ceiling for the reverse bias across either diode. For a 12 V automotive rail, this gives over 5× derating margin, which is comfortable for load-dump transients that can spike above 40 V. On a 24 V truck or industrial bus, the margin is still 3×, so this diode fits standard 12 V and 24 V systems without needing a higher-voltage (100 V) Schottky that would carry a larger Vf penalty. The 100 nA maximum reverse leakage at 50 V keeps standby draw negligible in battery-backed circuits. ## Forward voltage and current rating — application fit Forward voltage is specified at 1 V maximum at 15 mA. The 70 mA average rectified current per diode limits each diode to light loads: think I²C bus protection, GPIO clamp, or a low-current sensor supply OR-ing, not a power-supply output rectifier. The Small Signal =< 200 mA speed classification confirms this is a switching diode, not a power rectifier — it is built for fast recovery in signal-path and low-current switching roles. ## Package and footprint: SOT-23-3 common-cathode pinout The BAS70-05B5000 uses the standard SOT-23-3 land pattern (TO-236-3 / SC-59 variant) with the Infineon-specific PG-SOT23-3-3 supplier package code. This is the same pinout as the industry-standard BAS70-05 family, so it drops onto any existing BAS70-05 footprint without a layout change. The SOT-23 body is 2.9 mm × 1.3 mm, MSL 1 per the Infineon Schottky family — no bake required before reflow if the reel seal is intact.","metaTitle":"Infineon BAS70-05B5000 Schottky Diode, 70 V, 70 mA, AEC-Q101","metaDescription":"Infineon BAS70-05B5000 dual common-cathode Schottky diode, 70 V reverse voltage, 70 mA average rectified current per diode, AEC-Q101 qualified, SOT-23 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","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","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dcbfe13fac2f72abdc51427ff9f52c64.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent or pin-compatible alternative to the BAS70-05B5000?","answer":"The standard BAS70-05 (non-automotive) is footprint- and pin-compatible but lacks the AEC-Q101 qualification.
