About this product
The 1N4004 is a 1 A, 400 V general-purpose silicon rectifier diode in the SMA surface-mount package, the SMD version of the classic 1N400x series. It is commonly used in AC-to-DC rectifiers, reverse-polarity protection, and as a flyback diode across relay coils and motor windings.

Frequently asked questions
What is the price of 1N4004 SMA SMD General Purpose Rectifier Diode 1A 400V in Egypt?
1N4004 SMA SMD General Purpose Rectifier Diode 1A 400V currently costs 0.75 EGP in Egypt.
Where can I buy 1N4004 SMA SMD General Purpose Rectifier Diode 1A 400V in Egypt?
1N4004 SMA SMD General Purpose Rectifier Diode 1A 400V is available from Makers Electronics. Compare the offers above to find the best price.
Can I use the 1N4004 as a flyback diode for a relay or DC motor?
Yes, this is a common use. Connect the banded end (cathode) to the positive supply side and the anode to the switched side of the coil, so the diode conducts the inductive kick-back current when the switch opens.
What voltage does the 1N4004 handle and where is it not suitable?
It is rated for 400 V reverse voltage and 1 A average current, with about 1.1 V forward drop at 1 A. Its recovery is slow, so it is not intended for high-frequency switching; use a Schottky or fast-recovery diode there.
