Each diode handles up to 200 mA average rectified current and blocks 80 V DC reverse. The 4 ns reverse recovery time makes it useful for high-speed switching, snubbing, and logic-level steering where a single dual package saves board area. The 80 V reverse voltage rating gives comfortable headroom on 24 V and 48 V rails, and the 4 ns trr means the diode recovers fast enough for switching supplies running into the low-MHz range. Forward voltage drop is 1.25 V max at 150 mA, which is typical for a small-signal silicon diode at this current — expect about 0.9 V at lower currents. Reverse leakage is 150 nA at 70 V, negligible for most signal and bias circuits. Infineon lists the BAV70E6433HTMA1 as Last Buy. That means the manufacturer has stopped regular production and is fulfilling final orders through a last-time-buy window. Once that window closes, the part will be unavailable through the factory channel. For a production BOM, this is the signal to qualify a replacement or secure lifetime-buy inventory now. ## SOT-23 footprint and field-swap reality The SOT-23-3 package (PG-SOT23) is a standard surface-mount footprint. Orientation is unambiguous: the common-cathode pin (pin 3) is typically the tab side. On a field repair without a hot-air station, a fine-tip iron and tweezers can swap it — the three leads are on 0.95 mm pitch, so there is enough room to wick solder from each pad. No special ESD precautions beyond the usual wrist strap.","metaTitle":"Infineon BAV70E6433HTMA1 dual switching diode, 80 V, 4 ns","metaDescription":"Infineon BAV70E6433HTMA1 small-signal dual common-cathode diode. 80 V reverse, 4 ns trr, 200 mA per diode.

The base product number BAV70 covers many variants from multiple manufacturers (Nexperia, onsemi, Diodes Inc) in SOT-23 with the same common-cathode pinout and similar 80 V / 200 mA / 4 ns ratings. Any of those can serve as a functional drop-in, but you should verify the marking code and date code against your incoming inspection criteria."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BAV70E6433HTMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BAV70E6433HTMA1 when reusing this data.
