What is 1N4001 means: 1N4001 series diodes are 1 Ampere current handling general purpose rectifier diode. 1N is stands for American standard semiconductor (Generic name) with ONE JUNCTION.
400X Series like 4001,4002 to 4007 is indicates the voltage, current and power rating of the diodes.
1N= Means One Junction between P-type and N-Type.
400= Means Serial number of the rectifier.
1= Means Defines its (1 A) current rating.
The diodes are used to convert AC into DC these ares used as Half and Full wave rectifier.
When selecting to circuit take 3 points given below.
