The STLD200N4F6AG from STMicroelectronics is an N-channel 40V MOSFET for automotive motor- control applications, reverse battery protection and high-performance power switching.

The device, housed in a PowerFLATTM Dual-Side Cooling package measuring 5mm x 6mm, has the same footprint and thermally efficient base as the standard PowerFLAT package. But it also has an exposed top-side source electrode, which enhances its ability to dissipate heat.

The device is rated to carry a maximum continuous drain current of 120A. At a drain current of 75A and a gate-source voltage of 10V, the device’s maximum drain-source on-resistance is rated at 1.5mΩ, providing for high energy efficiency and easing system thermal management.

In addition, total gate charge of 172nC at a drain current of 90A and a gate-source voltage between 0V and 10V, combined with low input and output capacitance values, results in efficient switching at high operating frequencies.

FEATURES

  • AEC-Q101 qualified
  • 3.5V maximum gate threshold voltage
  • High avalanche ruggedness
  • Low gate-drive power loss
  • Wettable flanks package for 100% automatic optical inspection

APPLICATIONS

  • Switching power supplies
