The diode's low junction capacitance — 3 pF at 0 V, 1 MHz — suits it for high-speed switching in signal and protection circuits. The 120 mA forward current is a continuous average rating; peak repetitive currents can be higher if the duty cycle is low, but the 150°C junction temperature limit governs the thermal budget. The 1 µA reverse leakage at 30 V is typical for a small-signal Schottky — expect it to double every 10°C above 25°C junction, so budget leakage in high-temperature environments. ## AEC-Q101 qualification and the sourcing angle The lifecycle is listed as active, so no near-term end-of-life risk for production builds.","metaTitle":"Infineon BAS40B5003 Schottky Diode, 40 V, 120 mA, AEC-Q101","metaDescription":"Infineon BAS40B5003 Schottky diode, 40 V reverse voltage, 120 mA forward current, AEC-Q101 qualified, 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":"3pF @ 0V, 1MHz","Supplier Device Package":"PG-SOT23-3-3","Current - Reverse Leakage @ Vr":"1 µA @ 30 V","Voltage - DC Reverse (Vr) (Max)":"40 V","Current - Average Rectified (Io)":"120mA","Operating Temperature - Junction":"150°C","Voltage - Forward (Vf) (Max) @ If":"1 V @ 40 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.0300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8f6cd2d3ea2609775832c074f4cfd4da.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAS40B5003/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BAS40B5003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BAS40B5003 when reusing this data.
