IRLR7843PBF Description

Short technical summary and product information.

The Infineon IRLR7843PBF is a HEXFET Power MOSFET suitable for high-frequency synchronous buck converters and isolated DC-DC converters with synchronous rectification. It features very low RDS(on) at 4.5V VGS and ultra-low gate impedance.

 

Key electrical characteristics include a Drain-to-Source Breakdown Voltage (BVDSS) of 30V and a maximum Static Drain-to-Source On-Resistance (RDS(on)) of 3.3mΩ at 25°C. The continuous drain current is rated at 161A at 25°C and 113A at 100°C (VGS @ 10V). The maximum power dissipation is 71W at 25°C.

 

This MOSFET is available in D-Pak and I-Pak packages, both surface mountable. It operates within a temperature range of -55°C to +175°C.

 

The device is designed for applications requiring high efficiency and performance in power conversion systems.
