IRFU120PBF Description

Short technical summary and product information.

The IRFU120PBF is an N-Channel power MOSFET from Vishay Siliconix, designed for fast switching and rugged performance. It features a maximum drain-source voltage of 100V and continuous drain current of 7.7A at 25°C (4.9A at 100°C). The device offers a low on-resistance of 270mOhm at 10V gate drive.

 

This MOSFET is suitable for a variety of power switching applications including DC-DC converters, motor control, and power supplies. It exhibits typical gate charge of 16nC total, with 4.4nC gate-source and 7.7nC gate-drain, enabling efficient switching at moderate frequencies.

 

Packaged in the TO-251AA (IPak) through-hole package, the IRFU120PBF is designed for straightforward PCB mounting. It also supports repetitive avalanche energy up to 4.2mJ and single pulse avalanche energy of 210mJ, indicating robust performance under inductive loads.

 

Operating temperature range is -55°C to 150°C, with maximum power dissipation of 42W at case temperature 25°C and 2.5W at ambient 25°C on PCB.
