The IRLR7843TRPBF is an N-Channel HEXFET power MOSFET from Infineon Technologies, designed for high-efficiency power conversion applications. It offers a drain-source breakdown voltage of 30V and a continuous drain current of 161A at 25°C case temperature.
Key electrical characteristics include a maximum on-resistance of 3.3mOhm at 15A and 10V gate drive, a total gate charge of 50nC at 4.5V, and an input capacitance of 4380pF at 15V drain-source voltage. The device is capable of dissipating up to 140W at 25°C case temperature.
This MOSFET is optimized for high-frequency synchronous buck converters used in computer processor power supplies, as well as isolated DC-DC converters with synchronous rectification for telecom and industrial equipment. The lead-free (PbF) package supports RoHS compliance.
The device is housed in a surface-mount DPAK (TO-252) package with three leads and a tab, and operates over a junction temperature range of -55°C to 175°C.
