It comes in a surface-mount SC-70 / SOT-323 package (supplier device package PG-SOT323). With a reverse recovery time of 100 ps, it is suited for high-speed switching applications where a PN-junction diode's stored charge would be a problem — think low-power rectification, freewheeling, and signal clamping in battery-operated or portable equipment. Infineon lists the BAS4005WE6327BTSA1 as obsolete. For BOM lines already qualified to this part, the only supply route is the surplus and broker market. ## What the 100 ps trr means for the circuit The 100 ps reverse recovery time is the key differentiator here. A standard switching diode in the same current class would have a trr in the nanosecond range. That speed matters when the diode is used in a switching regulator's bootstrap or snubber, or in a high-frequency rectifier stage where reverse-recovery losses eat into efficiency. The Schottky barrier gives you essentially no stored charge to sweep out, so the turn-off is effectively instantaneous at these signal-level currents. ## Package and footprint fit The SC-70 / SOT-323 footprint (PG-SOT323) is a common small-signal package. If you are replacing this part on an existing board, the land pattern matches the standard SOT-323 layout.","metaTitle":"Infineon BAS4005WE6327BTSA1 Schottky Diode, 40V, 120mA","metaDescription":"Infineon BAS4005WE6327BTSA1 Schottky diode, 40V Vr, 120mA Io per diode, common cathode pair, 100 ps trr, SC-70.","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)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAS4005W","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"PG-SOT323","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/44df76da5149267357870826728c6c92.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the best replacement for BAS4005WE6327BTSA1?","answer":"Infineon has not published an official replacement for the BAS4005WE6327BTSA1. A functionally similar part would be a dual common-cathode Schottky diode rated for at least 40 V and 120 mA per diode in an SC-70 package.
