Diodes - Rectifiers - Single

The A1N5404G-G is a 1A, 400V power rectifier diode commonly used in AC circuits, offering steady performance and durability. A rectifier in a DC power supply once rectified the AC mains voltage to a pulsating DC, and the secondary part of the power supply filters the pulsating waveform to provide the output DC voltage. Also called a one-way valve, the A1N5404G-G works by allowing forward current flow while blocking the reverse current direction. It uses v-shaped semiconductor material to pass current.

General Features

• Epoxy molded package
• Low forward voltage drop
• High forward surge current capability
• High current rating

Applications

The A1N5404G-G is commonly used in DC power supplies, adapter circuits, switching power supplies, voltage rectifiers, TV sets, electronic ballasts and damping circuits.

Operation Principle

The operation of the A1N5404G-G is relatively straightforward. When the anode is connected to the positive terminal of a power source and the cathode to the negative terminal, ideal current flow is from the anode to the cathode. This produces a forward voltage drop (a voltage loss) of about 0.7V. Reverse current flow is prevented due to the diode\'s v-shaped semiconductor material, which blocks current when the anode is connected to the ground or negative voltage, or the cathode is connected to the positive terminal.

For effective operation, the A1N5404G-G has a maximum average forward current rating of 1A, while the maximum forward voltage drop is 0.7V at that current. The device is capable of handling a maximum repetitive peak reverse voltage of 400V, while the peak non-repetitive surge current rating is 200A.

Conclusion

The A1N5404G-G is a 1A, 400V power rectifier diode with a low forward voltage drop, high current rating, and high forward surge current capability. Its application fields include DC power supplies, adapter circuits, switching power supplies, voltage rectifiers, TV sets, electronic ballasts and damping circuits. Operation of the device relies on its v-shaped semiconductor material, which allows forward current flow while blocking reverse current flow.
