1N5408 Diode Standard Recovery Rectifier, 1000 V, 3.0 A

1N5408 is a diode of 1N540x series. It is a general purpose diode with many good features which makes it ideal to use in wide variety of general purpose applications. For example it is capable of handling maximum 3A or 3000mA of current across it.

It is also an ideal diode if you are looking for a little bit more ampere handling capabilities as compare to DO-41 diodes for example 1N4007, 1N4148 etc. In most applications you can replace these diodes with 1N5408 to get more forward current.

A 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 cathode terminal can be identified by using a grey bar.

The b is called a power diode because of its high forward current and reverse voltage with a power dissipation of 6.25W. For 1N5408 Diode, the maximum current carrying capacity is 3A it withstand peaks up to 200A.

Hence we can use this in circuits that are designed for less than 3A. The reverse current is 10uA which is negligible. These diodes have a slow recovery time so in modern electronics it is being replaced by other advanced diodes.
