This topology is commonly used for high-speed signal clamping, steering, and snubbing in low-power DC circuits — think I/O protection on logic lines, flyback catch diodes in relay drivers, or polarity protection in compact portable designs. The 150 nA leakage at 70 V keeps standby losses negligible in battery-powered equipment. The 4 ns reverse recovery time is the spec that separates this diode from a general-purpose rectifier. It means the diode can switch from forward conduction to reverse blocking in under 5 ns, which is fast enough to clamp transients on a 10 MHz digital bus or snub the inductive kick from a small relay without introducing excessive switching loss. For comparison, a standard 1N4148 signal diode is typically around 4 ns as well — the BAV99W series is in the same speed class, but the dual series package saves board space and placement cost. ## Obsolete — how to source it now Infineon lists the BAV99WE6327BTSA1 as obsolete. The part ships in a SC-70 / SOT-323 package (Infineon designates it PG-SOT323). It is a three-lead surface-mount package with a 1.3 mm pitch — small enough for dense layouts but still hand-solderable with care. If you are replacing a BAV99 in a different package (SOT-23, for instance), the footprint is not the same — SOT-323 is roughly 2.0 x 1.25 mm versus SOT-23 at 2.9 x 1.3 mm, so a layout change is required.","metaTitle":"BAV99WE6327BTSA1 Dual Series Diode, 80 V, 4 ns trr, SOT-323","metaDescription":"Infineon BAV99WE6327BTSA1 dual series switching diode, 80 V reverse voltage, 4 ns trr, 200 mA average rectified current, 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); Cut Tape (CT)","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":"$0.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c754167409a9cf53396e78b08b433586.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAV99WE6327BTSA1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for BAV99WE6327BTSA1?","answer":"For a pin-compatible alternative, look at the BAV99 series in SOT-323 from other manufacturers (e.g., Nexperia, ON Semiconductor) — the base BAV99W topology is standardized across vendors, but verify the specific suffix and package code against your BOM."},{"question":"What are the specifications of BAV99WE6327BTSA1?","answer":"It is a standard dual series switching diode rated for 80 V reverse voltage, 200 mA average rectified current per diode, 4 ns reverse recovery time, 150 nA leakage at 70 V, and 1.25 V forward drop at 150 mA.
