Product details

Overview

DMN2005UFGQ-7 from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for 50A continuous drain current at TC = +25°C, with R_DS(ON) of 4.6 mΩ at V_GS = 4.5V and qualified to AEC-Q101 for automotive motor control and load switching applications.

For engineers reviewing the DMN2005UFGQ-7 datasheet, DMN2005UFGQ-7 pinout, DMN2005UFGQ-7 application, or DMN2005UFGQ-7 equivalent, key selection criteria include low-voltage gate drive compatibility (2.5V–4.5V), thermally efficient small-form-factor packaging, and robust unclamped inductive switching performance in high-reliability automotive power stages.

Technical Context

This MOSFET employs planar trench-gate technology optimized for low R_DS(ON) and fast switching in 12V/24V automotive systems. Its gate threshold voltage (0.4–1.2V) enables reliable turn-on with logic-level drivers, while its 100% production-tested UIS capability ensures survivability under inductive load transients.

The PowerDI3333-8 package delivers R_θJC = 6.1°C/W and supports 2.27W power dissipation on 2oz copper FR-4 with thermal bias-enabling compact DC-DC converter and motor driver designs without external heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20 V - Supports 12V nominal automotive rails with margin against load-dump transients.
R_DS(ON) @ 4.5V	4.6 mΩ - Enables <1.5W conduction loss at 18A, critical for thermally constrained motor drivers.
I_D (TC = 25°C)	50 A - Sustains peak motor stall currents without derating in properly heatsinked layouts.
Q_g @ 4.5V	68.8 nC - Low gate charge reduces driver power and enables efficient PWM operation up to 500 kHz.
E_AS	58.4 mJ - Confirmed repetitive avalanche energy rating ensures reliability in inductive switching without snubbers.
T_J Range	−55°C to +150°C - Fully specified across full automotive temperature range per AEC-Q101.

Pinout & Package

Package: PowerDI3333-8 - thermally enhanced 8-pin surface-mount package with exposed drain paddle, 33% smaller board area than SO-8, UL 94V-0 molding compound, and matte tin annealed terminals.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7	Drain (D)	Internally paralleled drain connections tied to exposed thermal pad - primary current path and thermal interface to PCB.
8	Source (S)	Single-source terminal - connects to ground reference and provides return path for load current.
G (Gate)	Gate (G)	Exposed gate pad located between pins 4 and 5 - requires controlled trace routing to minimize ringing and EMI.

Key Features

Feature	Design Value
Low R_DS(ON) at 2.5V	8.7 mΩ - enables direct drive from 3.3V microcontrollers in space-constrained body control modules.
100% UIS tested	23.9 A I_AS, 58.4 mJ E_AS - eliminates need for external clamping diodes in solenoid and relay drivers.
Thermal efficiency	R_θJC = 6.1°C/W - allows >2× higher power density vs. SO-8 equivalents in same PCB footprint.
AEC-Q101 qualification	PPAP-capable with full automotive reliability testing - meets requirements for ASIL-B functional safety subsystems.

Applications

Motor Control

Load Switch

Use Scenario: Driving brushed DC motors in automotive seat/mirror actuators with PWM at 20 kHz.

IC Role / Device Role / Timing Role: High-side or low-side power switch controlling motor direction and speed via duty-cycle modulation.

Use Scenario: Replacing mechanical relays in battery disconnect circuits for ADAS ECUs.

IC Role / Device Role / Timing Role: Solid-state load switch managing 12V main power rail with controlled inrush and fault isolation.

Use Value: 100% UIS qualification ensures survival during hot-plug events and cable short-circuits without external protection.

DC-DC Converter

Automotive Lighting

Use Scenario: Synchronous rectifier in 12V-to-5V buck converter for infotainment head units.

IC Role / Device Role / Timing Role: Low-side synchronous FET operating at 300–500 kHz with gate drive synchronized to high-side switch.

Use Value: 68.8 nC total gate charge minimizes driver losses and enables use of low-cost dual MOSFET drivers like DIODES AP2112.

Use Scenario: LED current regulation in adaptive front lighting systems (AFS) with dynamic beam shaping.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC010N04LS6	R_DS(ON) = 1.0 mΩ @ 4.5V (lower), but 40V V_DSS and larger TSDSON-8 package.	Better efficiency in 24V systems; less suitable for ultra-compact 12V modules due to 30% larger footprint.	Select when lower conduction loss outweighs board area constraints and 24V system margin is required.
ON Semiconductor NTMFS4C09NT1G	R_DS(ON) = 4.8 mΩ @ 4.5V (nearly identical), but only AEC-Q101 qualified in specific lots-not PPAP-capable by default.	Requires additional qualification effort for Tier-1 automotive programs; no guaranteed PPAP support.	Select only for non-PPAP industrial or aftermarket applications where AEC-Q101 compliance is sufficient but not production-certified.

Compared with BSC010N04LS6 and NTMFS4C09NT1G, the DMN2005UFGQ-7 uniquely balances ultra-low R_DS(ON), AEC-Q101 + PPAP readiness, and minimal 3.3 mm × 3.3 mm footprint-making it optimal for volume automotive modules where supply chain assurance and layout density are co-priorities.

FAQ

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

The DMN2005UFGQ-7 supports 40A continuous drain current at TC = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerDI3333-8 package under sustained high-power operation without active cooling.

Is the gate threshold voltage compatible with 3.3V microcontroller outputs?

Yes-the gate threshold voltage ranges from 0.4V to 1.2V, ensuring reliable turn-on with standard 3.3V GPIOs. At V_GS = 3.3V, R_DS(ON) is approximately 5.2 mΩ (interpolated from typical curves), delivering strong conduction performance without level-shifting.

Does this MOSFET include an integrated body diode, and what is its forward voltage?

Yes-it features an intrinsic body diode with V_SD = 0.8–1.1V at 27A and 25°C. The diode is fully characterized for reverse recovery (t_RR = 16.1 ns, Q_RR = 8.5 nC), making it suitable for synchronous rectification and freewheeling in buck converters.

What is the recommended PCB pad layout for thermal performance?

Diodes specifies a 1-inch square 2oz copper thermal pad connected to the exposed drain paddle. Minimum recommended layout includes 2.37 mm × 3.70 mm central pad with eight 0.42 mm × 0.70 mm thermal vias spaced evenly-achieving R_θJA = 55°C/W per datasheet Note 7.
