The IRF7811A is an N-Channel MOSFET from Infineon Technologies, part of the HEXFET chipset family. It is designed for DC-DC converter applications, particularly as a control FET in synchronous buck converters. The device offers a drain-source voltage rating of 28V and a continuous drain current of 11A at 25°C.
Key electrical characteristics include a maximum on-resistance of 10mOhm at 10V gate drive and a typical gate charge of 17nC for synchronous FET operation. The device is housed in an 8-SOIC surface-mount package with a maximum power dissipation of 2.5W at 25°C ambient. The operating junction temperature range is -55°C to 150°C.
The IRF7811A is optimized for low conduction and switching losses, making it suitable for high-efficiency power conversion. It is 100% tested for parameters critical in synchronous buck converters, including on-resistance, gate charge, and Cdv/dt-induced turn-on immunity.
The drain-source voltage rating is 28V.
The continuous drain current is 11A at 25°C ambient temperature.
The maximum on-resistance is 10mOhm at Vgs=10V and Id=11A.
The IRF7811A is available in an 8-SOIC (0.154", 3.90mm Width) surface-mount package.
The operating junction temperature range is -55°C to 150°C.
The IRF7811A is listed as RoHS3 Compliant, but this data is unverified and has low confidence.
