Product details

Overview

DMN6040SFDEQ-7 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in U-DFN2020-6 (Type E) package, qualified to AEC-Q101 for automotive use. It delivers 38 mΩ R_DS(ON) @ V_GS = 10 V, 6.5 A continuous drain current at T_A = +25°C, and supports DC-DC converters and backlighting power management with 0.6 mm profile and 4 mm² PCB footprint.

For engineers reviewing the DMN6040SFDEQ-7 datasheet, DMN6040SFDEQ-7 pinout, DMN6040SFDEQ-7 application, or DMN6040SFDEQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, low-profile U-DFN2020-6 thermal performance (R_θJA = 61 °C/W with copper plate), 100% UIS-tested ruggedness, and dual gate-drive capability at 4.5 V and 10 V.

Technical Context

This MOSFET operates as a high-reliability, surface-mount power switch optimized for automotive-grade DC-DC conversion and LED backlighting. Its 60 V BVDSS rating enables operation across 12 V and 24 V vehicle electrical systems, while the 38 mΩ/47 mΩ R_DS(ON) values at V_GS = 10 V / 4.5 V support efficient synchronous rectification and PWM-driven load control.

The device integrates a robust body diode (V_SD = 0.7–1.2 V, Q_RR = 11.9 nC) and exhibits fast switching dynamics (t_D(ON) = 6.6 ns, t_D(OFF) = 20.1 ns) with low gate charge (Q_g = 10.4 nC @ 4.5 V). Its thermal design targets junction temperatures from –55°C to +150°C under PPAP-supported production flow.

Key Specifications

Use Scenario: Constant-current regulation of multi-string automotive LED arrays using buck topology.

IC Role / Device Role: Synchronous rectifier in high-efficiency DC-DC converter output stage.

Use Value: 38 mΩ R_DS(ON) minimizes conduction loss at 6.5 A; 0.6 mm height fits within slim headlamp housing constraints.

Start-Stop System Power Management

Infotainment Display Backlight

Use Scenario: Managing battery-to-load power paths during engine cranking events with voltage dips down to 6 V.

IC Role / Device Role: High-side or low-side load switch protecting downstream 5 V/3.3 V rails from brownout conditions.

Use Value: 60 V BVDSS withstands load-dump transients up to ISO 7637-2 Pulse 5a; 150 °C T_JMAX supports under-hood placement.

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
DMN6040SFDE-7	Same die, non-AEC-Q101 rated; no PPAP documentation; identical R_DS(ON), Q_g, and package	Not suitable for automotive production; acceptable for industrial prototypes or cost-sensitive non-automotive designs	Select only if AEC-Q101 compliance and PPAP support are not required
NTMFS4C06NT1G	60 V, 3.5 mΩ @ 10 V (lower R_DS(ON)), SO-8FL package (larger footprint, higher R_θJA)	Better conduction efficiency but requires more board area and thermal vias; lacks U-DFN2020-6's 0.6 mm profile	Choose when lower on-resistance outweighs size constraints and automotive qualification is secondary

Compared with DMN6040SFDEQ-7, DMN6040SFDE-7 offers identical electrical specs but no automotive qualification, while NTMFS4C06NT1G trades superior R_DS(ON) for larger size and higher thermal resistance-making DMN6040SFDEQ-7 optimal for space-limited AEC-Q101-compliant designs.

FAQ

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

At T_A = +100°C, the DMN6040SFDEQ-7 supports 2.7 A continuous drain current (derated from 5.3 A at 25°C per the datasheet's steady-state ID vs. T_A curve). This assumes FR-4 board with 1-inch² copper and accounts for R_θJA = 61 °C/W and T_JMAX = 150°C.

Does this MOSFET require a gate resistor for automotive PWM switching?

A gate resistor (typically 5–22 Ω) is recommended to dampen ringing and limit peak gate current during 10.4 nC charge/discharge cycles. The device's 1.2 Ω intrinsic gate resistance and low Crss (44 pF) reduce risk of oscillation, but external damping ensures robustness against EMI in noisy vehicle environments.

Can DMN6040SFDEQ-7 be used in high-side configuration?

Yes-it supports high-side switching when driven by a bootstrap or isolated gate driver capable of delivering ≥10 V to the gate relative to the source. Its ±20 V V_GSS rating and 60 V BVDSS allow safe operation with source potentials up to 60 V below drain, provided gate drive remains referenced correctly.

Is the U-DFN2020-6 (Type E) package compatible with standard reflow profiles?

Yes-the package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260°C, 20–40 sec above 217°C). Its NiPdAu plating ensures solderability per MIL-STD-202 Method 208, and the 0.6 mm profile avoids tombstoning on fine-pitch layouts.
