Product details

Overview

DMTH3004LFGQ-7 from Diodes Incorporated is a 30V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI3333-8 package, with R_DS(ON) = 5.5 mΩ @ V_GS = 10V, 75A continuous drain current at T_C = +25°C, and AEC-Q101 qualification - deployed in engine management systems and DC-DC converters for high-reliability automotive power stages.

For engineers reviewing the DMTH3004LFGQ-7 datasheet, DMTH3004LFGQ-7 pinout, DMTH3004LFGQ-7 application, or DMTH3004LFGQ-7 equivalent, key selection criteria include its 175°C junction rating, low 4.1 mΩ typical R_DS(ON), 100% UIS avalanche robustness, thermally efficient PowerDI3333-8 footprint, and AEC-Q101 PPAP-capable qualification for under-hood automotive use.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) while maintaining fast switching via minimized Q_gd × R_DS(ON) figure-of-merit (FOM) of ~1.0 nC·mΩ. Its 3.3 mm × 3.3 mm PowerDI3333-8 package features an exposed drain pad for direct thermal coupling to PCB copper, enabling R_θJC = 3°C/W.

The device supports gate drive at 4.5V (R_DS(ON) = 8.5 mΩ max) and 10V (5.5 mΩ max), with V_GS(TH) = 1–3V and guaranteed 100% unclamped inductive switching up to I_AS = 27A (E_AS = 110 mJ) - critical for load dump and motor control transients.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - Maximum blocking voltage compatible with 24V automotive battery systems including load dump peaks.
R_DS(ON) @ 10V	4.1–5.5 mΩ - Enables <1.5W conduction loss at 75A, reducing heatsink requirements in high-current DC-DC phases.
I_D (T_C = 25°C)	75 A - Package-limited continuous current supporting high-power body control modules and starter solenoid drivers.
T_J Max	+175°C - Rated for under-hood operation without derating in engine bay environments exceeding 125°C ambient.
Q_g @ 10V	44 nC - Low gate charge enables efficient 100–500 kHz switching in synchronous buck regulators with minimal driver loss.
E_AS	110 mJ - Avalanche energy rating ensures survivability during inductive turn-off events in motor gate drivers and solenoid controls.
R_θJC	3°C/W - Thermal resistance from junction to case allows direct mounting to copper pour for >40W dissipation without external heatsink.

Applications

Engine Management Systems

Body Control Modules

Use Scenario: High-side fuel injector driver in gasoline direct injection (GDI) systems requiring precise 1–5 ms pulse width control at 12–24V supply.

IC Role / Device Role / Timing Role: N-channel high-side switch with integrated body diode for freewheeling; operates in linear and saturated modes during current ramp-up and hold phases.

Use Value: Low R_DS(ON) reduces on-state power loss by >40% vs. legacy TO-252 devices, enabling single-layer PCB layout without thermal vias.

Use Scenario: Power distribution switch for HVAC blower motors, seat heaters, and lighting loads in centralized body control units.

IC Role / Device Role / Timing Role: Load switch with overcurrent and thermal shutdown protection; used in conjunction with external current sense and MCU-based diagnostics.

Use Value: 175°C rating allows placement directly on main power board near fuse box, eliminating remote mounting and interconnect losses.

DC-DC Converters

Start-Stop Systems

Use Scenario: Synchronous rectifier in 48V–12V bidirectional buck-boost converter for mild hybrid vehicles.

IC Role / Device Role / Timing Role: Low-side synchronous FET with fast t_F = 8 ns and low Q_gd = 8 nC - critical for ZVS/ZCS transition efficiency at 300 kHz switching frequency.

Use Value: Q_gd × R_DS(ON) FOM of 1.0 nC·mΩ improves light-load efficiency by 2.3% compared to industry-standard 30V TrenchFETs.

Use Scenario: Starter motor pre-charge and main contactor replacement in 12V start-stop systems with regenerative braking energy recovery.

IC Role / Device Role / Timing Role: High-current power switch handling 500A+ inrush during cold cranking, with avalanche capability to absorb inductive kickback.

Use Value: E_AS = 110 mJ enables safe operation without external TVS, reducing BOM count and PCB space in compact junction boxes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB033N04LGATMA1	40V V_DSS, R_DS(ON) = 3.3 mΩ @ 10V, PG-HSOF-8 package, R_θJC = 2.3°C/W	Higher voltage margin but larger footprint and non-AEC-Q101 qualified for automotive production	Select when 40V system margin is required and AEC-Q101 is not mandated; verify thermal interface compatibility with HSOF-8 layout.
STL220N4LF7AG	40V V_DSS, R_DS(ON) = 2.2 mΩ @ 10V, PowerFLAT 5x6 package, AEC-Q101 qualified	Lower R_DS(ON) but higher Q_g (65 nC) and no 175°C rating - limited to T_J ≤ 150°C	Prefer for ultra-low-loss 48V systems where ambient temperature stays below 105°C; avoid in engine bay locations.

Compared with IPB033N04LGATMA1 and STL220N4LF7AG, DMTH3004LFGQ-7 uniquely balances 30V optimization, 175°C operation, AEC-Q101 compliance, and PowerDI3333-8 thermal density - making it the only choice for space-constrained, high-ambient automotive power switches requiring full production validation.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The DMTH3004LFGQ-7 supports 52 A continuous drain current at T_C = +100°C, per the Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerDI3333-8 package's internal construction and solder joint reliability under sustained high-temperature operation.

Is the body diode suitable for reverse recovery in synchronous rectification?

Yes - the body diode has t_RR = 25 ns and Q_RR = 37 nC at I_F = 15 A and di/dt = 500 A/μs, enabling use in synchronous buck topologies up to 500 kHz. Its soft recovery characteristic minimizes voltage overshoot during commutation.

Does this MOSFET require gate resistors for automotive EMI compliance?

Yes - a 3 Ω gate resistor is specified in the dynamic test conditions (t_D(ON), t_R) and recommended for EMI suppression. Combined with the device's low Q_gd = 8 nC, this value balances switching speed and radiated emissions in 12V/24V harness environments.

How does the PowerDI3333-8 package compare thermally to DFN5x6?

PowerDI3333-8 achieves R_θJC = 3°C/W - comparable to DFN5x6 - but with 33% less board area and optimized for single-sided assembly. Its exposed drain pad connects directly to inner-layer copper, whereas DFN5x6 often requires multiple thermal vias for equivalent performance.
