Texas Instruments N-Channel Power MOSFET, 40V, 50A, VSON-8

The Texas Instruments N-Channel Power MOSFET is designed using NexFET™ technology to minimise losses in a wide range of power conversion applications, offering high efficiency and reliable performance. Its ultra-low gate charge (Qg) and gate-to-drain charge (Qgd) are key features that significantly reduce switching losses, making it an excellent choice for high-frequency DC-to-DC converters.

This surface-mount MOSFET is constructed with a halogen-free plastic package and is avalanche-rated for robustness in demanding conditions. It features a logic-level gate drive, simplifying interface with control circuits, and operates across a broad junction temperature range from -55°C to 150°C.

Primary Applications

• DC-to-DC Conversion: Ideal for primary-side switching and secondary-side synchronous rectification in switch-mode power supplies (SMPS).
• Battery-Powered Systems: Efficiently manages power in portable devices and battery management systems.
• Motor Control: Provides precise and efficient drive control for brushed and brushless DC motors in industrial and consumer applications.
