It is rated for a DC reverse voltage of 70 V and an average rectified current of 70 mA per diode, with a forward voltage drop of 1 V at 15 mA. The reverse recovery time is specified at 100 ps, making it suitable for high-speed switching and RF clamping applications where fast turn-off is needed. Typical uses include protection clamping in mixed-signal circuits, high-speed switching power supplies, and signal steering in telecom or instrumentation front ends. ## Obsolete — sourcing reality for sustainment programs The BAS 70-04 B5003 carries an obsolete lifecycle status. The 100 ps reverse recovery time allows the diode to switch off faster than most standard Schottky diodes, which matters in high-frequency rectification or snubber circuits where stored charge causes losses.","metaTitle":"BAS 70-04 B5003 Schottky Diode, 70 V 70 mA, SOT-23, Obsolete","metaDescription":"Infineon BAS 70-04 B5003 dual series Schottky diode, 70 V reverse voltage, 70 mA average rectified, 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)","Diode Type":"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 70","Diode Configuration":"1 Pair Series Connection","Supplier Device Package":"PG-SOT23","Reverse Recovery Time (trr)":"100 ps","Current - Reverse Leakage @ Vr":"100 nA @ 50 V","Voltage - DC Reverse (Vr) (Max)":"70 V","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1 V @ 15 mA","Current - Average Rectified (Io) (per Diode)":"70mA (DC)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9526b7a29b9d9392c22535f40c22dc52.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BAS 70-04 B5003 obsolete and what is its replacement?","answer":"Yes, the BAS 70-04 B5003 is listed as obsolete. No official replacement order code is provided in the product record. For a form-fit-function substitute, evaluate the standard BAS 70-04 (without the B5003 suffix) in the same SOT-23 package — it shares the same die and electrical ratings, though the tape-and-reel suffix may differ. Confirm pin compatibility and electrical specs against your design before substituting."},{"question":"Where can I buy BAS 70-04 B5003 available via RFQ confirmation?","answer":"No stock count or price is published here."},{"question":"What are the electrical specifications of BAS 70-04 B5003?","answer":"It is a dual series Schottky diode rated for 70 V DC reverse voltage, 70 mA average rectified current per diode, 1 V forward drop at 15 mA, 100 nA reverse leakage at 50 V, and a reverse recovery time of 100 ps.
