IRFR48ZPBF

IRFR48ZPBF Description

The IRFR48ZPBF from Infineon Technologies is an N-channel HEXFET® MOSFET designed for high-efficiency power switching applications. With a 55V drain-to-source voltage (Vdss) and 42A continuous drain current (Id), it delivers robust performance in demanding circuits. The device features an ultra-low on-resistance (Rds(on)) of 11mΩ at 10V gate drive, minimizing conduction losses and improving thermal management. Packaged in a DPAK (TO-252) surface-mount form factor, it is optimized for space-constrained designs while maintaining high power dissipation capability (91W at Tc).

IRFR48ZPBF Features

• Low Gate Charge (Qg): 60nC at 10V ensures fast switching and reduced drive losses, ideal for high-frequency applications.
• High Input Capacitance (Ciss): 1720pF at 25V balances switching speed with noise immunity.
• Wide Vgs Range: ±20V gate tolerance enhances reliability in varied drive conditions.
• Efficiency: Low Vgs(th) of 4V at 50µA enables compatibility with low-voltage control circuits.
• Robust Construction: ROHS3 Compliant and REACH Unaffected, meeting stringent environmental standards.
• Thermal Performance: MSL 1 (Unlimited) rating ensures suitability for extended storage and assembly processes.
