Frequently Asked Questions

Q: What is the difference between BAV70 and BAV99 transistors?

A: Both are dual SMD switching transistors in a SOT-23 package, but they differ in their internal diode configuration. The BAV70 has two diodes with a common cathode, while the BAV99 has two diodes in series. Both are rated at 0.2A / 70V, making them interchangeable in many applications depending on your circuit topology.

Q: Are these BAV70 and BAV99 components new and genuine?

A: Yes. This bulk pack contains new, original BAV70 (A4) and BAV99 (A7) components — not recycled, pulled, or remarked parts. They are manufactured in Mainland China and are suitable for professional SMD assembly and prototyping.

Q: What PCB assembly process are these components compatible with?

A: The SOT-23 3-pin SMD package is fully compatible with standard reflow soldering and hand-soldering workflows. It is one of the most widely used small-signal SMD packages, supported by virtually all pick-and-place and SMT assembly equipment.

Q: How are the 3000 pieces packaged for storage and use?

A: Components are supplied in standard tape-and-reel or bulk packaging suited for SMD assembly. This ensures the parts stay organised and protected from static or mechanical damage during storage and handling.
