Hello,
I want to use some signal diodes of type BAV99 for a sensor assembly with Arduino. That chip is too small for my eyes, I can not solder it.
Can I replace that chip with two loose diodes?

Maybe these

Use 1N4148

 

Yes, the 4148 would work as it has better recovery time than the BAV99. I would not use a general purpose rectifier like your ebay find.

 

Thanks!
