Designed for small-signal switching applications up to 200 mA, with a reverse voltage rating of 40 V and an average rectified current of 120 mA per diode. The 100 ps reverse recovery time makes it suitable for high-speed rectification, clamping, and protection circuits in low-power DC-DC converters, signal conditioning, and ESD protection. The 40 V reverse voltage (Vr) sets the maximum DC blocking voltage; stay below this in rectifier or protection roles. The 120 mA average rectified current per diode is the continuous load limit — if your circuit draws more, you need a higher-current Schottky or a parallel pair. The 100 ps trr is exceptionally fast, so this part handles high-frequency switching without significant reverse-recovery losses, but the 1 µA leakage at 30 V means it is not the lowest-leakage choice for battery-powered sense circuits. ## Obsolete status and sourcing reality Listed as Obsolete by Infineon. Availability is limited to existing stock and surplus channels. The SOT-23-3 package (also known as TO-236-3 or SC-59) is a small, three-lead surface-mount footprint. It is rework-friendly with a hot-air station — low thermal mass means it desolders quickly without lifting pads. The PG-SOT23 supplier device package is the same mechanical outline. Standard MSL 1 handling applies.","metaTitle":"BAS 40-06 B5003 Schottky Diode, 40 V, 120 mA, SOT-23-3","metaDescription":"Infineon BAS 40-06 B5003 dual common-anode Schottky diode, 40 V Vr, 120 mA Io, 100 ps trr, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Schottky","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAS 40","Diode Configuration":"1 Pair Common Anode","Supplier Device Package":"PG-SOT23","Reverse Recovery Time (trr)":"100 ps","Current - Reverse Leakage @ Vr":"1 µA @ 30 V","Voltage - DC Reverse (Vr) (Max)":"40 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1 V @ 40 mA","Current - Average Rectified (Io) (per Diode)":"120mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/44df76da5149267357870826728c6c92.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAS%2040-06%20B5003/alternatives.json"},"ai":{"faq":[{"question":"What is a suitable replacement for BAS 40-06 B5003?","answer":"There is no direct Infineon replacement listed for this obsolete part. A common cross-shop candidate is the BAT54S, which is also a dual Schottky in SOT-23-3 but uses a series configuration rather than common anode. Verify pin compatibility for your board layout. For a common-anode alternative, consider the BAS40-05 (common cathode) or BAS40-06 (common anode) from other manufacturers in the same SOT-23-3 footprint, but confirm electrical ratings match your circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BAS-40-06-B5003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BAS-40-06-B5003 when reusing this data.
