Does anyone know the switching speed of 1n400x diodes or where to find it? Can't find it in normal specs.
thanks

Typical trr is in the 1-20usec range, tfr as much as a microsecond, depending on conditions.
If you care about it exactly, you probably shouldn't be using this kind of diode.

If you are going to use them for more than a few hundred Hz, then you should use a diode made for fast switching, like the 1N4933 thru 37.
Normally trr is 30 usec.
Or the UF400x, which requires even less thinking, and has trr in the
50-75ns range.Best regards, Spehro Pefhany

Fairchild, Vishay and various generic makers. Eg. Mouser has Fairchild UF4004 parts for USD $56/1000.
