IRFR3806PBF

IRFR3806PBF Description

The IRFR3806PBF from Infineon Technologies is a N-channel HEXFET® MOSFET designed for high-efficiency power switching applications. With a 60V drain-to-source voltage (Vdss) and 43A continuous drain current (Id), it delivers robust performance in demanding environments. This surface-mount device features a low on-resistance (Rds(on)) of 15.8mΩ at 10V gate drive, minimizing conduction losses and improving thermal management. Packaged in a DPAK (TO-252) tube, it is optimized for automated assembly and high-power-density designs.

IRFR3806PBF Features

• Low Rds(on): 15.8mΩ @ 25A, 10V ensures efficient power handling with reduced heat generation.
• High Current Capability: 43A (Tc) rating supports high-load applications.
• Fast Switching: Low gate charge (Qg = 30nC @ 10V) and input capacitance (Ciss = 1150pF @ 50V) enhance switching speed.
• Wide Vgs Range: ±20V gate-to-source voltage tolerance for flexible drive compatibility.
• Robust Thermal Performance: 71W (Tc) power dissipation rating ensures reliability under high stress.
• Industry-Standard Compliance: ROHS3, REACH unaffected, and MSL 1 (unlimited) for environmental and handling safety.
