The IN4007 diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible. The power dissipation of this diode is 3W.
