FDB42AN15A0 Description

Short technical summary and product information.

The FDB42AN15A0 is an N-Channel PowerTrench MOSFET from ON Semiconductor (originally Fairchild Semiconductor). It is designed for high-efficiency power conversion and demanding automotive applications.

Key electrical specifications include a maximum drain-source voltage of 150V, continuous drain current of 35A at Tc=25°C, and a low on-resistance of 42mΩ maximum (36mΩ typical) at Vgs=10V, Id=12A. The device features a low gate charge of 33nC typical and low Miller charge for fast switching performance. It is rated for single pulse avalanche energy of 90mJ.

The MOSFET is housed in a surface mount D²PAK (TO-263) package with a junction-to-case thermal resistance of 1.0°C/W. It operates over a junction temperature range of -55°C to 175°C. The part is qualified to AEC Q101 automotive reliability standards.

Typical applications include DC/DC converters, offline UPS systems, distributed power architectures, primary switches for 24V and 48V systems, high voltage synchronous rectification, and automotive load control such as direct injection and electronic valve train systems.
