How can I calculate the maximum switching frequency of a diode?

[tastychickenwings69]

Hi.
I have a RFN10NS8D super fast recovery diode and wanna calculate the maximum working frequency.
I was planning on using it for some HF AC rectification tests.
The trr reverse recovery time is 40ns.

datasheet:

Help would be nice.

You cant. All the datasheet gives you is typ. and max. Reverse Recovery Times (Trr) for the reverse current to drop to 25% of its initial peak.  You have to decide what proportion of the reverse half-cycle you can tolerate it conducting for without excessive losses, and, allowing for any asymmetry in the waveform, decide what *YOU* regard as its frequency limit in *YOUR* application.
