The BUK9M3R3-40HX is a MOSFET N-channel logic level MOSFET in LFPAK33 package manufactured by Nexperia. It is designed for use in load switching, logic level shifting, and load current control in switching mode power supplies, DC-DC converters, cell phone transmitters, and PLCs. The device has a low on-resistance of 3.3 mO and a breakdown voltage of 40 V. It provides low gate-source threshold at 2.3 V and zero gate charge to reduce turn-on losses. The maximum continuous drain current is 75 A at a maximum junction temperature of 175 °C. This MOSFET operates with a low gatesource voltage of 1.8 V and is certified to the RoHS and REACH standards.
