BUK9V13-40HX

The BUK9V13-40HX is a dual N-channel logic level MOSFET from Nexperia, employing Trench 9 TrenchMOS technology. It is housed in an LFPAK56D package with a half-bridge configuration, where the source of the high-side FET is internally connected to the drain of the low-side FET, simplifying PCB layout for motor drive applications. The device is AEC-Q101 qualified for automotive use.

Key electrical specifications include a maximum drain-source voltage of 40 V, continuous drain current of 42 A (at Tmb = 25°C), and total power dissipation of 46 W. The typical on-resistance is 13.6 mΩ at VGS = 10 V and ID = 10 A. The logic level gate allows operation at lower gate voltages, with a maximum gate threshold voltage of 2.2 V. Input capacitance is 1160 pF maximum at VDS = 25 V.

The LFPAK56D package features gull wing leads for automated optical inspection and copper clip construction for high robustness. It is designed for surface mount assembly and occupies a compact footprint suitable for space-constrained designs. The operating junction temperature range is -55°C to 175°C.

Typical applications include 12 V automotive systems such as powertrain, chassis, body, and infotainment modules, as well as brushless and brushed DC motor drives, DC-to-DC converters, and LED lighting.
