IRFP4468
The IRFP4468 MOSFET from Infineon Technologies is an N‑channel transistor rated at 100 V and 290 A, designed for efficient switching in power electronics. With an on-resistance of 2.6 mΩ, it minimizes conduction losses and maintains thermal stability, making it suitable for synchronous rectification, motor control, DC-DC converters, and renewable energy systems. Its TO-247AC package supports effective heat dissipation, and it can operate at temperatures up to 175 °C.
This MOSFET supports heavy loads while maintaining low conduction losses. Its total power dissipation of 520 W (with proper case cooling) and gate threshold voltage of 2.0–4.0 V enable integration into low-voltage drive circuits. The device provides fast switching and reliable operation for applications such as UPS, inverters, and motor drives.
The IRFP4468 is built with avalanche-tested technology and is RoHS-compliant. Its design allows stable operation under high currents and harsh conditions. Engineers use this component in DC-DC converters, battery-management systems, and high-current switching applications where efficiency and reliability are important.
