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.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these BAV70 and BAV99 components new and genuine?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This bulk pack contains new, original BAV70 (A4) and BAV99 (A7) components — not recycled, pulled, or remarked parts.
