What is 1N4002 diode used for?
The 1N4002 are a very commonly used power diode and are often used for reverse voltage protection on DC input circuits and also used in many power applications such as DC-DC converters. The 1N4002 can handle up to 100V reverse voltage and up to 1A of continuous current with a surge peak of 30A.
Can diodes be used to convert AC to DC?
A single diode can transform AC power into an intermittent DC flow, but a bridge rectifier uses four diodes to reverse the direction of both sides of the AC pulse. With a bridge rectifier, the DC still oscillates from zero to a peak value, but it doesn’t cut out half the time.
What type of diode is 1N4002?
Rectifier diodes
| Model Number | Diode Type | Peak Inverse Voltage |

| 1N4002 | Rectifier | 100 V |
| 1N4003 | Rectifier | 200 V |
| 1N4004 | Rectifier | 400 V |
| 1N4005 | Rectifier | 600 V |
Does diode allow DC?
Diodes are also known as rectifiers because they change alternating current (ac) into pulsating direct current (dc). When a diode allows current flow, it is forward-biased. When a diode is reverse-biased, it acts as an insulator and does not permit current to flow.
What does a diode do in a DC circuit?
The primary purpose of a diode is to conduct electricity in one direction and not the other. When a diode is used with DC it either allows current to flow, or stops it. When it does allow current to flow the overall voltage is reduced by the diodes forward voltage drop.
What does Schottky diode do?
Schottky diodes are used for their low turn-on voltage, fast recovery time and low-loss energy at higher frequencies. These characteristics make Schottky diodes capable of rectifying a current by facilitating a quick transition from conducting to blocking state.
