Product details
Overview
DMN6040SSSQ from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in SO-8 package, rated for 60V VDSS, 40mΩ RDS(ON) @ 10V VGS, and 5.5A continuous drain current at +25°C. It delivers low conduction loss and fast switching in automotive power management circuits including DC-DC converters and LED backlighting drivers.
For engineers reviewing the DMN6040SSSQ datasheet, DMN6040SSSQ pinout, DMN6040SSSQ application, or DMN6040SSSQ equivalent, key selection criteria include its AEC-Q101 qualification, 4.5V gate drive capability (55mΩ RDS(ON)), 100% production-tested UIS robustness, and SO-8 thermal performance (RθJA = 61°C/W with recommended layout).
Technical Context
This MOSFET employs a planar trench-gate structure optimized for low RDS(ON) and controlled Qg (22.4nC @ 10V), enabling efficient hard-switching in synchronous buck stages. Its body diode exhibits trr = 18ns and Qrr = 11.9nC under 100A/μs dI/dt, supporting high-frequency flyback recovery.
The device operates across –55°C to +150°C junction temperature, with VGS(th) tightly specified (1–3V) and stable over temperature (±0.2V variation from –55°C to +150°C). Its Ciss = 1287pF and Crss = 44pF support predictable gate drive design with minimal Miller-induced shoot-through risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - Withstands up to 60V drain-source blocking voltage before avalanche onset, suitable for 48V automotive bus and 24V industrial rails. |
| RDS(ON) @ 10V | 40mΩ max - Delivers ≤220mW conduction loss at 5.5A, enabling compact thermal design in space-constrained modules. |
| RDS(ON) @ 4.5V | 55mΩ max - Ensures reliable turn-on with standard 5V logic-level gate drivers, critical for low-voltage control in infotainment systems. |
| Qg @ 10V | 22.4nC - Enables <10ns turn-on delay (tD(on)) with 6Ω gate resistor, supporting >1MHz switching in high-efficiency converters. |

Use Value: Low 1.2Ω gate resistance supports precise slew-rate control via RC gate network; SO-8 footprint fits tight board layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN6040SFD-13 | Same die, DFN3.3x3.3-8 package; RθJA = 45°C/W (vs. 61°C/W), no leaded pins. | Better thermal performance but requires rework of solder stencil and PCB layout; not pin-compatible with SO-8. | Select for higher-power density designs where thermal budget is tighter and lead-free assembly is mandatory. |
| IPB050N06N3 G | 60V, 5.0mΩ RDS(ON) @ 10V, TO-263 package; 3× lower RDS(ON) but 3× larger footprint and 2× higher Qg. | Higher current handling (80A pulsed) but unsuitable for space-constrained automotive modules due to size and thermal mass. | Select only when >10A continuous current or extreme thermal cycling durability is required; not drop-in for SO-8 footprints. |
Compared with DMN6040SFD-13, the DMN6040SSSQ trades 16°C/W higher RθJA for leaded SO-8 manufacturability and legacy compatibility; versus IPB050N06N3G, it sacrifices RDS(ON) for 60% smaller board area and faster switching in mid-power applications.

FAQ
Is DMN6040SSSQ qualified for automotive use?
Yes, DMN6040SSSQ is fully AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It supports PPAP documentation and meets automotive change control requirements, including temperature cycling, humidity testing, and mechanical shock validation per AEC standards.
What is the maximum continuous drain current at 100°C ambient?
At TA = +100°C with the recommended FR-4 PCB layout (2oz copper, minimum pad), the maximum continuous drain current is 2.7A. This is derived from the 2.0W power dissipation rating and RθJA = 61°C/W, yielding TJ = 100°C + (2.7A)2 × 0.04Ω × 61°C/W ≈ 149°C, within the 150°C limit.
Does DMN6040SSSQ require a gate resistor for stability?
Yes, a series gate resistor (typically 5–10Ω) is recommended to dampen ringing caused by LGS/Ciss resonance and prevent spurious turn-on from dv/dt coupling. The device's 1.2Ω intrinsic gate resistance alone is insufficient for robust EMI control in high-speed switching applications.
Can DMN6040SSSQ be used in parallel configurations?
Yes, its positive temperature coefficient of RDS(ON) (increasing with junction temperature) enables inherent current sharing when paralleled. However, matched gate drive paths and symmetrical PCB layout are required to ensure balanced dynamic current distribution and avoid thermal runaway.
