I'm currently working on a sensor project for a colleague in Mechanical Engineering and part of the circuit design that he gave me from his adviser's graduate thesis contains a precision rectifier like the one shown below.

I found this circuit on this website as well in another thread.
The circuit should respond at 100 kHz and I'm using the LF356 Op-Amp. Does anyone have any recommendations for high speed diodes? Thanks very much in advance!

edit: I am looking at digikey and mouser but I'm not entirely sure which parameters will give me the response I'm looking for. I found the one below... but not sure if it will work.
