NTMD4840NR2G

Overview

The NTMD4840NR2G is a dual N-channel enhancement mode MOSFET manufactured by onsemi. It utilizes silicon technology and is housed in an SOIC-8 surface-mount package. The device features a drain-source breakdown voltage (Vds) of 30 V and a continuous drain current (Id) of 4.5 A at 25°C. Its maximum drain-source on-resistance (Rds(on)) is 28 mΩ, measured at a gate-source voltage of 10 V. The component operates with a gate-source voltage range of ±20 V and has a threshold voltage (Vgs(th)) of 1.5 V. Key switching parameters include a gate charge (Qg) of 4.8 nC, a rise time of 5 ns, and a fall time of 3 ns. Power dissipation is rated at 1.95 W, with an operating temperature range from -55°C to +150°C.

Feature Summary

• Dual channel configuration for space-efficient circuit designs
• Low on-resistance characteristics for efficient power handling
• Fast switching performance suitable for high-frequency applications

Applications

• Power management circuits requiring dual N-channel control
• DC-DC converter topologies utilizing low-voltage MOSFETs
• Load switching applications in consumer electronics

Procurement Notes

Verify the current lifecycle status before procurement, as the component is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any sourced units are genuine and match the specified SOIC-8 package and electrical parameters. Check for moisture sensitivity level compliance if storage conditions have been compromised.

Selection Notes

Select this component when a dual N-channel MOSFET with a 30 V rating and approximately 4.5 A current capacity is required in an SOIC-8 package. Consider the 28 mΩ on-resistance for thermal management in low-voltage applications. Verify that the 4.8 nC gate charge aligns with the driving capability of the control logic. Compare against single-channel alternatives if pin count reduction is not a priority.

Part Context

This part belongs to the NTMD4840N series of dual N-channel MOSFETs from onsemi. It is designed for general-purpose switching applications where board space is limited. The series typically targets cost-sensitive consumer and industrial markets. The NR2G suffix indicates specific packaging and tape-and-reel specifications defined by the manufacturer.

Replacement Considerations

Check for direct replacements within the NTMD4840N family. Evaluate other dual N-channel MOSFETs with similar 30 V, 4.5 A, and SOIC-8 specifications from alternative manufacturers. Ensure pinout compatibility and electrical parameter equivalence before substitution.
