DMN3009SFG-13 Equivalent & Substitute Parts

Part Overview

The DMN3009SFG-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 30V drain-to-source voltage with 16A continuous drain current (Ta) and 45A (Tc). This device is housed in a 8-PowerVDFN surface mount package and is designed for power switching applications requiring compact form factors and efficient thermal management. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from alternative manufacturers while maintaining electrical and mechanical compatibility within specified parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the DMN3009SFG-13 is determined by the following critical parameters:

Electrical Compatibility Requirements:

Drain-to-Source Voltage (Vdss) must equal or exceed 30V
Continuous drain current rating must support the application's current demands
RDS(on) characteristics must be compatible with thermal and efficiency requirements
Gate threshold voltage and gate charge must be compatible with driver circuitry
Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Requirements:

Surface mount mounting type
Package footprint compatibility (8-PowerVDFN or equivalent)
Pin configuration alignment

Compliance Requirements:

ROHS3 compliance status
Active product status

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications from the same manufacturer) and manufacturer-recommended alternatives (functionally compatible parts from different manufacturers with comparable performance characteristics).

Engineering Selection Recommendations

DMN3009SFG-7 (Parametric Equivalent)

The DMN3009SFG-7 is a direct parametric equivalent to the DMN3009SFG-13, manufactured by Diodes Incorporated. All electrical specifications, including Vdss, continuous drain current, RDS(on), gate charge, and input capacitance, are identical. Both parts share the same 8-PowerVDFN package and surface mount configuration. Both are ROHS3 compliant with MSL 1 rating and active product status. The primary distinction is packaging format: DMN3009SFG-13 is supplied in Tape & Reel (TR) format with 9823 pieces in stock, while DMN3009SFG-7 is also supplied in Tape & Reel (TR) format with 1225 pieces in stock. This part is suitable for direct substitution in all applications where the DMN3009SFG-13 is specified.

STL11N3LLH6 (Manufacturer-Recommended Alternative)

The STL11N3LLH6, manufactured by STMicroelectronics, is a manufacturer-recommended alternative with comparable electrical characteristics within the 30V class. This device shares the same Vdss rating (30V) and operating temperature range (-55°C to 150°C). Key differences include lower continuous drain current (11A Tc versus 45A Tc), higher RDS(on) (7.5 mOhm versus 5.5 mOhm), lower gate threshold voltage (1.0V minimum versus 2.5V maximum), and reduced gate charge (17 nC versus 42 nC). The STL11N3LLH6 features lower input capacitance (1690 pF versus 2000 pF) and higher power dissipation capability (2W Ta, 50W Tc versus 900mW Ta). This part is suitable for applications where the lower current rating and different gate drive characteristics are acceptable. The STL11N3LLH6 is supplied in Cut Tape (CT) & Digi-Reel® format with 20581 pieces in stock. Both parts are ROHS3 compliant with MSL 1 rating and active product status.

Frequently Asked Questions (FAQ)

Q: Can the DMN3009SFG-7 be used as a direct replacement for the DMN3009SFG-13?

A: Yes. The DMN3009SFG-7 is a parametric equivalent with identical electrical specifications, package type, and compliance certifications. No circuit modifications are required for substitution.

Q: What are the key differences between the DMN3009SFG-13 and STL11N3LLH6?

A: The primary differences are continuous drain current (16A/45A for DMN3009SFG-13 versus 11A for STL11N3LLH6), RDS(on) (5.5 mOhm versus 7.5 mOhm), gate threshold voltage (2.5V versus 1.0V), and gate charge (42 nC versus 17 nC). The STL11N3LLH6 has lower input capacitance and higher power dissipation capability. Selection depends on application current requirements and driver compatibility.

Q: Are all three parts pin-compatible?

A: All three parts use the 8-PowerVDFN package with identical pin configurations, enabling direct PCB footprint compatibility.

Q: What packaging formats are available for these parts?

A: DMN3009SFG-13 and DMN3009SFG-7 are supplied in Tape & Reel (TR) format. STL11N3LLH6 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly process requirements and volume considerations.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain active product status. All are suitable for applications requiring these compliance certifications.

Q: Which substitute part should be selected for high-current applications?

A: The DMN3009SFG-7 maintains identical current ratings to the DMN3009SFG-13 (16A Ta, 45A Tc) and is the appropriate choice for applications requiring these current levels. The STL11N3LLH6, with 11A Tc rating, is suitable only for applications with lower current requirements.

Q: How do gate charge differences affect circuit design?

A: Gate charge (Qg) determines the charge required to switch the FET on or off. The DMN3009SFG-13 and DMN3009SFG-7 require 42 nC at 10V, while the STL11N3LLH6 requires only 17 nC at 4.5V. Lower gate charge reduces driver power dissipation and enables faster switching. Driver selection must accommodate the specific gate charge of the chosen device.

Q: Can the STL11N3LLH6 be used in applications designed for the DMN3009SFG-13?

A: Substitution is application-dependent. The STL11N3LLH6 is suitable only if the application's continuous drain current requirement does not exceed 11A (Tc) and if the different gate drive characteristics are compatible with the driver circuit. Applications requiring the full 16A or 45A rating must use the DMN3009SFG-13 or DMN3009SFG-7.
