IRFU3410

IRFU3410 Description

The IRFU3410 from Infineon Technologies is an N-channel HEXFET® MOSFET designed for high-efficiency power switching applications. With a 100V drain-to-source voltage (Vdss) and a continuous drain current (Id) of 31A (Tc), this device is optimized for robust performance in demanding environments. Its low on-resistance (Rds(on)) of 39mOhm at 10V gate drive ensures minimal conduction losses, while the ±20V maximum gate-source voltage (Vgs) provides flexibility in drive circuitry. The 1690pF input capacitance (Ciss) and 56nC total gate charge (Qg) contribute to fast switching speeds, making it suitable for high-frequency applications.

IRFU3410 Features

• High Power Handling: Supports 110W (Tc) power dissipation, enabling reliable operation under high thermal loads.
• Low Rds(on): 39mOhm @ 18A, 10V reduces energy loss and improves efficiency.
• Fast Switching: Optimized gate charge and capacitance for quick turn-on/off transitions.
• Robust Construction: Through-hole (IPAK) package ensures mechanical durability and heat dissipation.
• Wide Vgs Range: ±20V tolerance enhances compatibility with various drive circuits.
• Obsolete Status: While no longer in production, it remains a viable choice for legacy designs or replacements.

IRFU3410 Applications

• Power Supplies: Ideal for DC-DC converters, SMPS, and voltage regulation due to low Rds(on) and high current handling.
• Motor Control: Suitable for H-bridge and PWM motor drives in industrial and automotive systems.
• Load Switching: Efficiently manages high-current loads in relays, solenoids, and actuators.
• Renewable Energy: Used in solar inverters and battery management systems for low-loss switching.
• Legacy Systems: A dependable replacement in older electronics requiring high-voltage MOSFETs.

Conclusion of IRFU3410

The IRFU3410 offers a balance of high voltage tolerance, low conduction losses, and robust thermal performance, making it a strong candidate for power electronics. While marked as obsolete, its HEXFET® technology and 31A current rating ensure it remains useful for repairs or niche applications. Engineers seeking a 100V MOSFET with efficient switching may still find value in this well-proven Infineon component.
