IRFR3709ZTRPBF Infineon Power MOSFET

The IRFR3709ZTRPBF from Infineon is a 30V N-channel HEXFET® MOSFET optimized for ultra-low conduction losses in high-current switching applications. For selection, its standout feature is an exceptionally low on-resistance of just 6.5mΩ at 10V, combined with an 86A continuous drain current rating, minimizing power loss and heat generation. The logic-level gate threshold of 2.25V enables direct drive from microcontrollers and low-voltage logic without level shifters. A gate charge of 26nC at 4.5V and 2330pF input capacitance allow fast, efficient switching. The D-Pak surface-mount package handles 79W power dissipation in a compact footprint. In application, it excels as a synchronous rectifier in high-efficiency DC-DC converters for servers and telecom equipment, a load switch in automotive body electronics, and motor drive in battery-powered tools. It is also ideal for power management in notebooks, point-of-load regulators, and VRM modules where minimizing conduction losses and maximizing power density are critical.
