BYV29F/BYV29X series ultrafast rectifier diodes are intended for use in switched mode power supply output rectification, electronic lighting ballasts and high frequency switching circuits in general.
The BYV29F and BYV29X series are ultrafast epitaxial rectifier diodes designed for switched‑mode power supplies, electronic lighting ballasts, and high‑frequency switching circuits. The BYV29F devices are supplied in an SOD100 package, while the BYV29X devices use an SOD113 package.
Key electrical characteristics include low forward voltage drop, fast switching (t_r < 60 ns), and high thermal cycling performance. The datasheet provides detailed limiting values, isolation ratings, thermal resistance data, and mechanical dimensions for both package types.
