Introduction to 3N247-M4/51

The 3N247-M4/51 is a high power bridge rectifier diode with a 4 Amp nominal current rating and a maximum average rectified output current of 51 Amps and a reverse voltage of 630 volts. It is designed for general-purpose applications including power supplies and AC/DC converters.

Application Field of 3N247-M4/51

The 3N247-M4/51 is ideal for applications requiring fast, reliable and low-loss rectification. It is suitable for use in power supplies, AC/DC converters and other switching power applications. It is also suitable for high-efficiency AC/DC conversion as well as for battery charging and rectification steps in DC-DC converters.

Working Principle of 3N247-M4/51

The unique design of the 3N247-M4/51 helps it achieve an extremely low forward voltage drop, making it highly efficient while reducing the power dissipation. It is a four-terminal bridge rectifier, consisting of four p-type semiconductor rectifier diodes connected in a bridge configuration. It operates by rectifying AC current when a voltage is applied to the terminals. The AC current is converted to DC current by the diode bridge.When a voltage is applied across the terminals, the anode of one of the rectifier diodes will become the Positive pole and the anode of the other rectifier diode will become the Negative pole. The current will be supplied through the two rectifier diodes on the Negative pole, and then through two rectifier diodes on the Positive pole. The diode bridge performs the positive-negative voltage conversion and rectifies the alternating current in one step, allowing the current to pass in one direction only. It also reduces the power losses associated with the rectification process due to the low forward voltage drop of the diodes.

Conclusion

The 3N247-M4/51 is a four-terminal bridge rectifier diode, designed for general-purpose applications. It is ideal for power supplies, AC/DC converters, battery charging and rectification steps in DC-DC converters. It is designed for fast, reliable and low-loss rectification due to its extremely low forward voltage drop. Finally, it provides conversion of AC current to DC current in a single step, reducing power losses associated with the rectification process.
