IRFR5505PBF

IRFR5505PBF Description

The IRFR5505PBF from Infineon Technologies is a high-performance P-channel HEXFET® MOSFET designed for power management applications. With a 55V drain-to-source voltage (Vdss) and 18A continuous drain current (Id), it offers robust performance in compact surface-mount packages (DPAK). This MOSFET features a low on-resistance (Rds(on)) of 110mOhm at 10V gate drive, ensuring efficient power handling with minimal losses. Its ±20V maximum gate-source voltage (Vgs) provides flexibility in drive circuitry, while the 4V threshold voltage (Vgs(th)) ensures reliable switching.

IRFR5505PBF Features

• Low Gate Charge (Qg): 32nC at 10V reduces switching losses, improving efficiency in high-frequency applications.
• High Power Dissipation: 57W (Tc) enables reliable operation under demanding thermal conditions.
• Optimized Input Capacitance (Ciss): 650pF at 25V ensures fast switching and reduced gate drive requirements.
• Robust Construction: ROHS3 compliant and REACH unaffected, meeting stringent environmental standards.
• Surface-Mount DPAK Package: Ideal for space-constrained designs while maintaining excellent thermal performance.
