The last-time-buy period has passed, so new production lots are no longer available from the factory. Sourcing this part now means turning to the independent distribution channel, where verified date-code stock is quoted on request against an RFQ. Any lot offered should come with traceable date codes and a documented supply chain pedigree — mystery stock surfacing years after the official last-time-buy warrants extra scrutiny. ## Series Schottky pair — what the 5 ns trr buys you The BAT 54-04 B5003 integrates two Schottky diodes in a series configuration inside a single SOT-23-3 package. The 5 ns reverse recovery time is the headline switching spec: it lets this pair handle fast rectification in low-power DC-DC converters, flyback snubbers, and OR-ing diodes without the stored-charge penalty of a PN-junction part. ## SOT-23-3 footprint and thermal limits The series-connected die share the same junction temperature limit — thermal coupling means both diodes heat together under unbalanced current loads.","metaTitle":"Infineon BAT 54-04 B5003 Schottky Diode, 30 V, 200 mA","metaDescription":"Infineon BAT 54-04 B5003 Schottky diode pair, series config, 30 V reverse voltage, 200 mA, 5 ns trr, SOT-23 package.","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":"BAT 54","Diode Configuration":"1 Pair Series Connection","Supplier Device Package":"PG-SOT23","Reverse Recovery Time (trr)":"5 ns","Current - Reverse Leakage @ Vr":"2 µA @ 25 V","Voltage - DC Reverse (Vr) (Max)":"30 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"800 mV @ 100 mA","Current - Average Rectified (Io) (per Diode)":"200mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a679c07c291f154e3427f1312f9f8d50.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAT%2054-04%20B5003/alternatives.json"},"ai":{"faq":[{"question":"Is BAT 54-04 B5003 obsolete?","answer":"The last-time-buy window has closed, so new factory production is no longer available."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BAT-54-04-B5003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BAT-54-04-B5003 when reusing this data.
