Description

This MOSFET is designed to minimize the on-state resistance (R_DS(ON)) yet maintain superior switching performance, making it ideal for high-efficiency power-management applications.

Feature(s)

Low R_DS(ON)– Ensures On-State Losses Are Minimized
Small Form Factor Thermally Efficient Package Enables Higher Density End Products
ESD Protected Gate
Occupies Just 33% of the Board Area Occupied by SO-8 Enabling Smaller End Product
Wettable Flank for Improved Optical Inspection
Lead-Free Finish; RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
The DMT31M9LFVWQ is suitable for automotive applications requiring specific change control; this part is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. https://www.diodes.com/quality/product-definitions/

Application(s)

Backlighting
Power-management functions
DC-DC converters
