Hi, can anyone tell me what type of diode is the fastest switching diode? i want to find a diode to clip the negative peak of a nano-second pulse. what is the most suitable diode for sub-nano second switching? Thanks
When the term "fast switching diode" is used, it refers to it's reverse recovery time and not it's turn-on time. Finding turn-on time specs for diodes isn't exactly easy.

That is true. But the turn-on time for most signal diodes is quite fast and does not vary much with the fabrication process. That's why it is not generally specified.
Show a diagram of the circuit that the diode connects to. What is the impedance of the signal source to the diode? It's hard to make a recommendation without knowing those things.
