Product details

Overview

DMN3029LFG-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in POWERDI3333-8 package, rated for 30V V_DS, 18.6mΩ R_DS(on) at V_GS = 10V, and 8.0A continuous drain current (T_A = 25°C). It delivers low conduction loss and fast switching for compact DC-DC converters and LED backlighting circuits.

For engineers reviewing the DMN3029LFG-7 datasheet, DMN3029LFG-7 pinout, DMN3029LFG-7 application, or DMN3029LFG-7 equivalent, key selection criteria include R_DS(on) at 4.5V (26.5mΩ), 100% UIS avalanche rating, AEC-Q101 qualification, thermal resistance (62.5°C/W on 2"×2" PCB), and Green/RoHS-compliant matte tin terminations.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(on) while preserving gate charge (Q_g = 11.3nC at V_GS = 10V) and switching speed (t_D(off) = 19.5ns). Its 100% R_g testing ensures gate resistance consistency (2.0–3.0Ω), critical for parallel operation and EMI control.

The device integrates a body diode with V_SD = 0.7V at I_S = 1A and exhibits stable threshold voltage (V_GS(th) = 0.9–1.8V) across −55°C to +150°C ambient, enabling reliable turn-on in automotive-grade power management.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30V - supports 24V rail systems with 20% margin against transients
R_DS(on) @ V_GS = 10V	18.6mΩ - enables ≤1.5W conduction loss at 8A DC load
R_DS(on) @ V_GS = 4.5V	26.5mΩ - ensures robust operation with 5V logic-level gate drive
I_D (continuous, T_A = 25°C)	8.0A - sustains full-rated current on thermally enhanced PCB layout
Q_g	11.3nC - balances switching loss and drive strength for 500kHz–1MHz converters
R_θJA	62.5°C/W - requires ≥2"×2" 2oz copper pad for 150°C max junction temp at 2.07W
Avalanche Rating	100% UIS tested - withstands unclamped inductive switching without derating

Pinout & Package

Packaged in POWERDI3333-8: surface-mount, thermally enhanced 8-pin plastic case with exposed drain paddle (pins 1–4 and 5–8 are source/drain pairs), UL 94V-0 rated, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4	Source	Common low-side return path; electrically tied to exposed paddle for thermal conduction
5, 6, 7, 8	Drain	High-current output node; connected to internal die drain metallization and thermal pad
G (Gate)	Control input	Pin 1 is gate; isolated by 25V V_GS rating; low C_iss (580pF) reduces drive power

Key Features

Feature	Design Value

Thermally efficient package	62.5°C/W R_θJA - achieves 2.07W dissipation on standard FR-4, reducing heatsink dependency
AEC-Q101 qualification	Validated for automotive power stages - meets temperature cycling, HTRB, and UHAST requirements
Green RoHS compliance	Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - satisfies EU ELV and JGPSSI directives
100% R_g test	2.0–3.0Ω gate resistance - guarantees consistent Miller plateau timing for predictable turn-off

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3029LFG-13	Identical electrical specs; differs only in tape-and-reel packaging (3000 pcs vs. 2000 pcs)	No functional difference; selected for higher-volume production runs	Choose -13 for cost-per-unit optimization in >10k unit annual forecasts
DMN3029LSD-7	Same die, but in smaller POWERDI3333-8 variant with reduced thermal pad area; R_θJA = 75°C/W (vs. 62.5°C/W)	Limited to ≤1.5W continuous dissipation; unsuitable for 6.5A+ steady-state loads	Select only when board space is constrained and thermal budget permits 20% lower power handling

Compared with DMN3029LFG-13, the -7 variant offers identical performance with tighter inventory control for mid-volume builds; versus DMN3029LSD-7, it delivers 20% higher thermal capability without sacrificing footprint-critical for automotive and industrial 6–8A DC-DC stages.

FAQ

What is the maximum continuous drain current at 70°C ambient?

At T_A = +70°C with 2"×2" 2oz copper PCB, DMN3029LFG-7 supports 6.3A continuous drain current (V_GS = 10V) per the datasheet's Note 6. This reflects thermal derating from 8.0A at 25°C due to reduced heat dissipation capacity at elevated ambient temperatures.

Is the POWERDI3333-8 package lead-free and RoHS compliant?

Yes. DMN3029LFG-7 features matte tin annealed over copper leadframe, fully compliant with EU RoHS Directive 2011/65/EU and halogen/antimony-free "Green" specifications (<900ppm Br+Cl, <1000ppm Sb), verified per Diodes Incorporated's published definitions.

Does this MOSFET require a gate resistor for stability?

A gate resistor (typically 5–10Ω) is recommended to dampen ringing caused by L_g/C_iss resonance, especially in high-speed switching. The specified 2.0–3.0Ω R_g is intrinsic; external resistance controls dV/dt and EMI without compromising t_D(off) (19.5ns) or t_f (5.8ns).

Can DMN3029LFG-7 be used in synchronous rectification?

Yes. With its low R_DS(on) (18.6mΩ at 10V), fast switching (t_r = 4.6ns, t_f = 5.8ns), and integrated body diode (V_SD = 0.7V), it is suitable for synchronous rectification in buck converters up to 1MHz, provided gate drive voltage matches V_GS requirements and layout minimizes parasitic inductance.
