Product details
Overview
DMN4027SSDQ-13 from Diodes Incorporated is a 40V dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 7.1A continuous drain current at VGS = 10V, with RDS(on) = 27 mΩ (max), and qualified to AEC-Q101 for automotive power management. It integrates two matched silicon dies for synchronous buck or half-bridge configurations in DC-DC converters.
For engineers reviewing the DMN4027SSDQ-13 datasheet, DMN4027SSDQ-13 pinout, DMN4027SSDQ-13 application, or DMN4027SSDQ-13 equivalent, key selection criteria include dual-die thermal coupling, body diode recovery (trr = 12.1 ns), gate charge (Qg = 12.9 nC @ 10V), and automotive-grade gate voltage rating (±16V).
Technical Context
This dual MOSFET uses planar trench-gate silicon technology optimized for low conduction loss and fast switching in high-frequency synchronous rectification. Each channel operates independently with identical electrical specs: VBRDSS = 40V, VGS(th) = 1.0–3.0V, and body diode VSD = 0.86–1.1V at 7A.
Thermal design accounts for dual-die interaction: RθJA = 58°C/W when both dies are active (per Note 10), and RθJL = 53°C/W to drain lead-critical for PCB layout in motor control H-bridges where shared heat spreading is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBRDSS | 40 V - Maximum blocking voltage before avalanche; defines safe operating range in 24V automotive systems. |
| RDS(on) @ 10V | 27 mΩ max - Enables ≤1.4 W conduction loss at 7.1A, critical for thermally constrained DC-DC modules. |
| Qg @ 10V | 12.9 nC - Determines gate driver strength requirement; supports >1 MHz switching with moderate drive capability. |
| trr | 12.1 ns - Fast body diode recovery reduces shoot-through risk and EMI in synchronous buck topologies. |
| TJ Range | −55°C to +150°C - Validated operation across full automotive under-hood temperature envelope. |
| AEC-Q101 Qualified | Yes - Confirmed reliability for automotive powertrain and body electronics per stress test requirements. |
Pinout & Package
Package: SO-8 (Surface-mount, 8-pin, dual-row, 1.27 mm pitch), molded green plastic (UL 94V-0), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-side or low-side power path node; electrically isolated from D2 but thermally coupled on shared die substrate. |
| S1 | Source of Channel 1 | Return path for Channel 1; tied to internal source bond wire-requires separate PCB copper pour for thermal isolation if used asymmetrically. |
| G1 | Gate of Channel 1 | Control input referenced to S1; threshold 1.0–3.0V enables 3.3V/5V logic-level drive compatibility. |
| S2 | Source of Channel 2 | Independent return for Channel 2; not internally connected to S1-supports floating half-bridge or dual low-side configuration. |
| G2 | Gate of Channel 2 | Independent control input; matched timing (tD(on), tr) ensures synchronized switching with Channel 1. |
| D2 | Drain of Channel 2 | Second power switch node; symmetric RDS(on) and Qg enables balanced current sharing in parallel or complementary topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel topology | Two independent, matched MOSFETs in one SO-8 footprint-reduces board area vs. discrete pairs and improves layout symmetry in H-bridges. |
| Low RDS(on) @ 4.5V | 47 mΩ max - Ensures usable on-resistance with 5V gate drive, supporting legacy microcontroller outputs without level-shifting. |
| Fast body diode recovery | trr = 12.1 ns - Minimizes reverse recovery loss and voltage spikes during hard commutation in synchronous rectifiers. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS power supplies-no derating required for temperature or life cycle. |
Applications
| Motor Control | DC-DC Converters |
|---|---|
Use Scenario: Bidirectional 24V brushed DC motor drive in automotive seat/mirror actuators. IC Role / Device Role / Timing Role: Dual low-side switch controlling direction and PWM speed via independent G1/G2 inputs; D1/D2 connect to motor terminals. Use Value: Matched RDS(on) ensures equal forward/reverse torque; low Qg enables 20 kHz PWM without excessive gate drive loss. | Use Scenario: Synchronous buck converter for infotainment system 5V rail from 12V battery. IC Role / Device Role / Timing Role: High-side and low-side switch in single-phase topology; D1/S1 as high-side, S2/D2 as low-side with bootstrap gate drive. Use Value: 12.1 ns trr prevents cross-conduction; 27 mΩ RDS(on) maintains >92% efficiency at 5A load. |
| Backlighting | Power Management |
Use Scenario: LED backlight dimming in instrument cluster displays using constant-current buck topology. IC Role / Device Role / Timing Role: Low-side current-sense switch (S1/D1) with external shunt; G1 driven by PWM controller; Channel 2 unused or paralleled for higher current. Use Value: 47 mΩ @ 4.5V allows direct MCU PWM control; SO-8 thermal resistance (58°C/W dual-active) sustains 1.5W dissipation without heatsink. | Use Scenario: Dual-rail power distribution in ADAS camera module (3.3V + 1.8V LDO pre-regulation). IC Role / Device Role / Timing Role: Independent load switches enabling controlled power-up sequencing; G1/G2 driven by PMIC enable signals. Use Value: AEC-Q101 qualification ensures reliability across thermal cycles; 0.5 µA IDSS minimizes standby leakage in always-on domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3027LSDQ-13 | 30V VBRDSS, same RDS(on) (27 mΩ @ 10V), lower Qg (9.2 nC) | Not suitable for 40V bus systems; better for 12V-only applications with tighter gate drive constraints. | Select when system maximum VDS ≤ 30V and lower switching loss is prioritized over voltage margin. |
| IPD20N04S4-02 | 40V VBRDSS, 2.0 mΩ RDS(on) @ 10V, TO-252 package, single-channel | Single device only; requires two units and larger PCB area; superior thermal performance (RθJA = 40°C/W). | Choose for higher-current (>15A) or thermally demanding designs where SO-8 footprint is insufficient. |
Compared with DMN3027LSDQ-13 and IPD20N04S4-02, DMN4027SSDQ-13 uniquely balances 40V rating, dual-channel integration, and AEC-Q101 compliance in SO-8-making it optimal for space-constrained automotive DC-DC and motor control where voltage margin and layout simplicity are critical.

FAQ
What is the maximum gate-source voltage rating for DMN4027SSDQ-13 in automotive use?
The absolute maximum VGS is ±20V per datasheet, but AEC-Q101 qualification limits operational gate drive to ±16V to ensure long-term reliability under automotive temperature cycling and voltage transients. Exceeding ±16V risks accelerated gate oxide degradation in sustained operation.
Can DMN4027SSDQ-13 be used in a half-bridge configuration with bootstrapped high-side drive?
Yes-Channel 1 (D1/S1/G1) serves as the high-side switch with bootstrap gate drive, while Channel 2 (D2/S2/G2) functions as the low-side switch. The matched RDS(on) and timing parameters ensure symmetrical switching, and the SO-8 layout supports compact gate loop routing to minimize noise.
How does the dual-die thermal coupling affect power derating?
When both channels operate simultaneously, RθJA degrades to 58°C/W (vs. 70°C/W for single-channel operation). At 1.25W total dissipation, junction temperature rise is 72.5°C above ambient-requiring PCB copper area ≥25 mm² per drain pad and no adjacent heat sources for reliable 150°C TJ margin.
Is the body diode suitable for synchronous rectification without external Schottky replacement?
Yes-the body diode has trr = 12.1 ns and Qrr = 5.1 nC, enabling efficient synchronous rectification up to 1 MHz in buck converters. Its VSD = 0.86–1.1V at 7A is higher than Schottky diodes, but the integrated solution eliminates layout complexity and parasitic inductance of discrete alternatives.
