IRLR7843TRRPBF Description

Short technical summary and product information.

This component is an N-Channel power MOSFET from Infineon Technologies, part of the HEXFET family. It is designed for high-efficiency power conversion applications. The MOSFET features a maximum drain-to-source voltage of 30V and a continuous drain current of 161A at 25°C case temperature. The static drain-to-source on-resistance is typically 2.6mOhm and maximum 3.3mOhm at Vgs=10V, enabling low conduction losses.

 

The device offers a gate threshold voltage range of 1.4V to 2.3V, and a total gate charge of 34nC typical (50nC maximum) at Vgs=4.5V. Input capacitance is 4380pF typical at Vds=15V. These characteristics make it suitable for high-frequency switching applications, such as synchronous buck converters and isolated DC-DC converters with synchronous rectification.

 

Packaged in a surface mount DPAK (TO-252-3) case, the MOSFET supports solder reflow processes. It is rated for an operating junction temperature range of -55°C to 175°C and a maximum power dissipation of 140W at 25°C case temperature. The device is lead-free per the datasheet and is claimed to be RoHS and REACH compliant (unverified).
