The 4 ns reverse recovery time makes it suited for high-speed switching, clamping, and logic-level steering applications where fast turn-off is needed — think relay coil suppression, flyback snubbing on a 24 V industrial bus, or protecting a comparator input from overvoltage transients. The SOT-23 footprint is a common board-level component that reflow-solders without special handling; the PG-SOT23 supplier package variant is the Infineon-specific marking. The BAV 99 E6433 carries an official lifecycle status of Obsolete. The 80 V reverse voltage rating sets the maximum DC or repetitive peak reverse voltage the diode can block — adequate for 48 V telecom rails or 24 V industrial supplies with margin, but not for 120 V AC rectification. The 4 ns reverse recovery time is the headline switching spec: it determines how fast the diode can transition from forward conduction to reverse blocking, directly affecting switching losses in a 100 kHz+ converter or the clamping bandwidth in a high-speed data line protector. Forward voltage drop is 1.25 V at 150 mA — typical for a small-signal silicon diode, so power dissipation at 200 mA continuous in free air on a standard PCB will be about 250 mW, which the SOT-23 package handles with reasonable junction temperature margin up to 150°C.","metaTitle":"BAV 99 E6433 dual series switching diode, 80 V, 4 ns trr","metaDescription":"Infineon BAV 99 E6433 dual series switching diode in SOT-23. 80 V reverse voltage, 4 ns trr, 200 mA average rectified current.","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)","Technology":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BAV 99","Diode Configuration":"1 Pair Series Connection","Supplier Device Package":"PG-SOT23","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":"$0.3486","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1db8184ddc122584851e73f7add3ff46.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BAV%2099%20E6433/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for BAV 99 E6433?","answer":"No single Infineon successor order code is listed for the E6433 suffix variant.
