IRFR3707Z

IRFR3707Z Description

The IRFR3707Z from Infineon Technologies is a 30V N-channel HEXFET® MOSFET designed for high-efficiency power switching applications. With a continuous drain current (Id) of 56A (Tc) and an ultra-low on-resistance (Rds(on)) of 9.5mΩ at 15A, 10V, this MOSFET delivers superior performance in power management circuits. Its 30V drain-to-source voltage (Vdss) and ±20V gate-to-source voltage (Vgs) tolerance make it robust for various industrial and automotive applications. Although marked as obsolete, its reliability and performance remain relevant for legacy designs.
