BAV99 in Different Varieties by Diotec Semiconductor

diotecThe BAV99 device is a 3-pin steering diode that has small forward voltage, large breakdown voltage, and low capacitance. The BAV99 is a widely used small signal device in dual diode configuration. Its two diodes in series can be used for any kind of signal processing, and two parts can even form a bridge for high speed full wave rectifying. As different as the applications are the requirements on such device: High volume consumer devices require only low voltage levels, but especially low BOM costs. Industrial applications need higher power and voltage ratings, e. g. at 24 V industrial control units. Battery powered electronics must be operated with lowest possible leakage currents to allow for long stand-by times. In addition, parts might need full AEC-Q101 qualification, in case of automotive use.


  • Fast switching speed
  • High conductance
  • Surface mount package ideally suited for automatic insertion
  • Connected in series
  • AEC-Q101 qualified available
  • RoHS-compliant

Diotec offers the BAV99 series from now on in different varieties, perfectly matching your particular needs:

  • The BAV99-C in commercial grade, rather cost attractive and offering 70 V / 2.5 µA / 225 mW
  • The industrial grade BAV99, having 85 V / 1 µA / 350 mW
  • The AEC-Q101 qualified BAV99-AQ, again with 85 V / 1 µA / 350 mW
  • The “high end” voltage version BAV99L, with 100 V / 1 µA / 350 mW
  • The “low leakage” varieties BAV199 and BAV199-AQ, offering 85 V / 5 nA / 350 mW

Diotec Semiconductor AG company was founded in Heitersheim, Germany. Since the very beginning, it has dealt with manufacturing rectifying diodes and bridges. It is a renowned and recognized European brand. For more than 40 years, Diotec has been active in this highly competitive market. Innovations and customer service are the basis of their success.
