It is rated for 80 V DC reverse voltage and 200 mA average rectified current per diode, with a reverse recovery time of 4 ns. The part is a surface-mount device in the SC-70 / SOT-323 case (PG-SOT323 supplier package), suited for general-purpose switching, ESD clamping, and polarity protection in low-current signal paths. This exact suffix variant (BAV99WE6433BTMA1) is listed as obsolete. If your design can accept a different manufacturer or package suffix, the BAV99W function is broadly second-sourced; verify pin-compatibility and electrical ratings with the alternate datasheet before committing the change. ## 4 ns trr — what it buys you in a signal path The 4 ns reverse recovery time places this diode in the fast-switching class for small-signal work. It can cleanly clip fast transients, commutate low-current inductive loads, or serve as a steering diode in a logic-level multiplexer without introducing excessive storage delay. The 150 nA leakage at 70 V reverse bias is tight enough for battery-powered sense circuits where every microamp counts.","metaTitle":"Infineon BAV99WE6433BTMA1 Standard Diode, 80 V, 200 mA","metaDescription":"Infineon BAV99WE6433BTMA1 standard switching diode, 1 pair series, 80 V Vr, 200 mA Io, 4 ns trr, SC-70/SOT-323.","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":"Standard","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAV99W","Diode Configuration":"1 Pair Series Connection","Supplier Device Package":"PG-SOT323","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c754167409a9cf53396e78b08b433586.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BAV99WE6433BTMA1?","answer":"The base BAV99W function is a standard industry part available from multiple manufacturers (e.g., Nexperia, ON Semiconductor, Diodes Inc.) in the same SOT-323 footprint.
