IRF8721TRPBF Description

Short technical summary and product information.

The IRF8721TRPBF is an N-Channel power MOSFET from Infineon Technologies, part of the HEXFET family. It features a drain-to-source voltage rating of 30V and a continuous drain current of 14A at 25°C ambient temperature. The device offers a low typical on-resistance of 6.9 mΩ at Vgs=10V and Id=14A, with a maximum of 8.5 mΩ.

This MOSFET is designed for high-efficiency DC-DC converters, particularly as a control MOSFET in synchronous buck converters for notebook processors and isolated DC-DC converters in networking systems. Key electrical characteristics include a low gate charge of 8.3 nC typical at Vgs=4.5V, which helps reduce switching losses.

The device is housed in a standard SO-8 surface-mount package with a 3.90mm width. It is lead-free and RoHS3 compliant per the datasheet. The operating junction temperature range is -55°C to 150°C, with a maximum power dissipation of 2.5W at 25°C ambient.
