It also has low gate charge times, making it ideal for high-frequency applications.

Working Principle

The IRFR7740PBF operates by using the conventional MOSFET principle. When a gate voltage is applied to the transistor, it acts as a switch, allowing current to flow from the source to the drain. This action is known as channel formation, and it is dependent on the channel width between the source and drain, the gate-source voltage, and the gate-drain voltage. As the voltage applied on the gate increases, the current flowing between the source and drain increases, allowing more power to be transferred.

To maximize the current conduction capabilities of the IRFR7740PBF, it is important to consider the range of voltages it can handle. The voltage range it can handle ranges from -20V to +20V, so it can be used in high-voltage applications without the risk of damage. The maximum current it can handle is 130 A.

Conclusion

The IRFR7740PBF from International Rectifier is a type of n-channel high-voltage power MOSFET with integrated UltraFET processing technology. It offers excellent performance for applications requiring high current and high-frequency operations. It has a voltage range of -20V to +20V and can handle up to 130 A of current, making it a great choice for applications in the industrial, automotive, and power supply sectors.
