NTMFD4C20NT3G

Overview

The NTMFD4C20NT3G is a single N-channel power MOSFET manufactured by onsemi, designed for high-efficiency power switching applications. It utilizes advanced trench technology to achieve low on-resistance and fast switching speeds. The device is housed in an SO-8FL (5x6 mm) surface-mount package, which facilitates compact circuit board layouts while maintaining robust thermal performance. Key electrical characteristics include a drain-source breakdown voltage of 20V and a continuous drain current capability that supports demanding load requirements. The component is engineered to minimize conduction and switching losses, making it suitable for DC-DC converters and CPU power supply circuits where space and efficiency are critical constraints.

Feature Summary

• Low on-resistance reduces conduction losses for improved power efficiency
• Optimized gate charge and capacitance values lower driving loss
• Fast switching characteristics enhance overall system performance
• RoHS compliant and lead-free construction meets environmental standards

Applications

• CPU power supply modules
• DC-DC converter circuits
• General-purpose power switching

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm packaging type and tape-and-reel specifications. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before integration into regulated products.

Selection Notes

Select this component when a 20V N-channel MOSFET is required in an SO-8FL package. Evaluate thermal resistance parameters relative to the PCB copper area and heat dissipation strategy. Compare on-resistance at the intended gate drive voltage to ensure adequate efficiency for the target application load conditions.

Part Context

This part belongs to the NTMFS4 series of single N-channel power MOSFETs from onsemi. The series is characterized by the use of trench technology to deliver low RDS(on) within a compact 5x6 mm footprint. Variants within the series typically differ by breakdown voltage ratings and specific on-resistance values, catering to various low-voltage power management needs.

Replacement Considerations

Direct replacements must match the 20V rating, N-channel configuration, and SO-8FL package dimensions. Verify that substitute devices offer comparable RDS(on) and gate charge specifications to maintain original circuit performance and thermal behavior.
