1N4007 1A 1000V Rectifier Diode (Pack of 10)

1N4007 1A 1000V Rectifier Diode – Pack of 10

The 1N4007 is a general-purpose silicon rectifier diode rated for 1A forward current and 1000V reverse voltage, supplied as a pack of 10. It is the standard choice for power-supply rectification, reverse-polarity protection and flyback protection.

The silver band on the body marks the cathode (−). Current flows from anode to cathode only, which lets it block reverse voltage and protect your circuit.

Frequently Asked Questions

Is the 1N4007 rated 1W or 1A?
It is rated 1A average forward current. Power loss at full current is roughly 1W, which is why some listings call it a “1W” diode.

Which side is the cathode?
The end with the silver/grey band is the cathode (−).

How do I use it as a flyback diode for a relay?
Connect it in reverse across the relay coil — cathode to the positive side, anode to the transistor/negative side.

Can I use 1N4007 instead of 1N4001–1N4006?
Yes. All share the same 1A rating; the 1N4007 has the highest voltage rating, so it replaces any of them.
