Don't recognise that one .... Maybe UF4007 ?? Quite common.

Fast version of 1N4007

DBC

A fast diode turns off more rapidly from the conducting to the blocking mode (faster reverse recovery), when going from forward to reverse bias, then a normal diode. The turn on time of either type of diode is about the same.

If you do not use a high-speed diode in a circuit that has a high frequency, it will get HOT.

You could use a Schottky diode if you can live with the higher juction capacitance.
