Packaged in a standard SOT-23-3 surface-mount case. Reverse recovery time is specified at 100 ps, making this part suitable for RF detector circuits, mixer protection, and high-frequency rectification where switching losses must be minimised. Forward voltage drops to 1 V at 15 mA forward current, and reverse leakage is only 100 nA at 50 V, keeping power dissipation low in sensitive signal paths. ## Obsolete — last-time-buy and surplus sourcing Listed as obsolete by Infineon. Because production has ended, procurement relies on independent distribution and surplus inventory. ## Package and reflow considerations The SOT-23-3 package (Infineon code PG-SOT23) is a standard three-lead small-signal outline. It places cleanly with pick-and-place equipment and reflows on a standard lead-free profile without special handling. The common-cathode pair shares the centre pin as the cathode common, with the two anodes on the outer pins — a layout that simplifies PCB routing for dual-diode clamping networks.","metaTitle":"BAS 70-05 B5003 Schottky diode, 70 V, 70 mA, SOT-23-3","metaDescription":"Infineon BAS 70-05 B5003 dual common-cathode Schottky diode, 70 V reverse, 70 mA average, 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 Common Cathode","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":"What is the difference between BAS70-05 and BAS70-04?","answer":"The BAS70-05 is a common-cathode dual Schottky diode pair, while the BAS70-04 is a series-connected pair.
