A 1N4148 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode.
The maximum current carrying capacity is 300mA it can withstand peaks up to 2A. The speciality of this diode is its fast recovery time of 8ns at a forward current of 10mA, hence this diode is used in places where fast switching are involved.
