1n400x

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.

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