IRF7343PBF

FET, MOSFET Arrays Overview

The IRF7343PBF is a dual N- and P-channel enhancement mode MOSFET from the HEXFET series, manufactured by Infineon Technologies. It utilizes advanced silicon process technology to achieve ultra-low on-resistance within an SOIC-8 surface-mount package. The device supports a drain-source voltage of 55 V for both channels. Continuous drain current ratings are specified at 4.7 A for the N-channel and 3.4 A for the P-channel at 25°C. The typical on-resistance values are 50 mΩ for the N-channel and 105 mΩ for the P-channel. Gate charge is typically 24 nC for the N-channel and 26 nC for the P-channel at 10 V. The component operates within a temperature range of -55°C to +150°C with a maximum power dissipation of 2 W.
