The 80 V Vr(max) provides margin above typical rails. The 4 ns reverse recovery time limits the reverse current spike during commutation. The 200 mA average current per diode is a signal-level rating. For new designs or BOM fills, the standard BAV70 (common-cathode dual diode, same SOT-23 footprint, same 80 V / 200 mA / 4 ns ratings) is the functional replacement — it shares the same base product number and pinout.","metaTitle":"BAV 70 B5003 dual common-cathode switching diode, 80 V","metaDescription":"BAV 70 B5003 is an 80 V, 200 mA dual common-cathode switching diode with 4 ns reverse recovery time in SOT-23.","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)","Technology":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAV 70","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"PG-SOT23","Reverse Recovery Time (trr)":"4 ns","Current - Reverse Leakage @ Vr":"150 nA @ 70 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.25 V @ 150 mA","Current - Average Rectified (Io) (per Diode)":"200mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/381dbd14669d5b228362e5582ba97408.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAV%2070%20B5003/alternatives.json"},"ai":{"faq":[{"question":"Is BAV 70 B5003 obsolete and what are my alternatives?","answer":"Yes, the BAV 70 B5003 is marked obsolete. The direct alternative is the standard BAV70 dual common-cathode diode, which has the same SOT-23 footprint, 80 V reverse voltage, 200 mA current rating, and 4 ns trr. The BAV70 is active and widely stocked."},{"question":"Does BAV 70 B5003 have the same pinout as BAV70?","answer":"Yes. The BAV 70 B5003 and the standard BAV70 share the same base product number (BAV70) and the same common-cathode dual-diode configuration in the SOT-23-3 package. The pinout is identical."},{"question":"Can I use BAV99 as a substitute for BAV 70 B5003?","answer":"No, not as a direct drop-in. The BAV99 is a series-connected dual diode (common anode for one, common cathode for the other), whereas the BAV 70 B5003 is a common-cathode pair. The pinout and circuit function differ. For a common-cathode replacement, use the standard BAV70."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BAV-70-B5003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BAV-70-B5003 when reusing this data.
