Product details
Overview
DMN4027SSD-13 from Diodes Incorporated is a 40V dual N-channel enhancement-mode MOSFET in SO-8 package, featuring 27 mΩ RDS(on) at VGS = 10 V, 7.1 A continuous drain current at TA = +25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency synchronous rectifier or half-bridge switch in DC-DC converters and motor control stages.
For engineers reviewing the DMN4027SSD-13 datasheet, DMN4027SSD-13 pinout, DMN4027SSD-13 application, or DMN4027SSD-13 equivalent, key selection criteria include dual-die thermal coupling behavior, body diode reverse recovery charge (Qrr = 5.1 nC), gate charge profile (Qg = 12.9 nC @ 10 V), and SO-8 lead-frame thermal resistance (RθJA = 58°C/W with dual-die derating).
Technical Context
This dual N-channel MOSFET integrates two independent silicon dies in a single SO-8 package with shared thermal path but electrically isolated channels. Each channel supports 40 V VBRDSS, 1.0–3.0 V gate threshold, and exhibits fast switching (tr = 3.1 ns, tf = 7.5 ns) under 20 V VDD and 6 Ω gate resistance.
Its design targets high-frequency power conversion where low conduction loss (RDS(on) = 27 mΩ @ 10 V) and controlled dynamic losses (Ciss = 604 pF, Crss = 59.6 pF) must coexist. The device operates across –55°C to +150°C junction temperature range and meets AEC-Q101 stress test requirements for automotive under-hood use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBRDSS | 40 V - Maximum blocking voltage before avalanche conduction begins; defines safe operating range in 24 V automotive and 36 V industrial bus systems. |
| RDS(on) @ 10 V | 27 mΩ - Conduction loss of 1.35 W at 7.1 A DC, enabling >95% efficiency in 500 kHz buck converters with 10 mm² copper area. |
| ID (continuous) | 7.1 A @ 25°C - Sustained current capability per channel with SO-8 thermal limits; derates to 5.4 A at 70°C ambient. |
| Qg @ 10 V | 12.9 nC - Total gate charge required to fully turn on; determines minimum gate driver peak current (≥2.2 A for 6 ns rise time). |
| Qrr | 5.1 nC - Body diode reverse recovery charge; directly impacts switching loss and EMI in hard-switched topologies. |
| RθJA (dual) | 58°C/W - Junction-to-ambient thermal resistance when both dies operate simultaneously; sets maximum power dissipation at 2.14 W for 150°C TJ. |
Pinout & Package
Package: SO-8 surface-mount plastic package with matte tin-plated copper lead frame, UL 94V-0 rated molding compound, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-side or low-side power path connection; shares thermal pad with D2 for dual-die heat spreading. |
| S1 | Source of Channel 1 | Return node for Channel 1; electrically isolated from S2 but thermally coupled via substrate. |
| G1 | Gate of Channel 1 | Control input requiring 12.9 nC total charge to drive from 0 V to 10 V with minimal overshoot. |
| S2 | Source of Channel 2 | Independent return for Channel 2; enables floating-source configurations like high-side switches with bootstrap gate drive. |
| G2 | Gate of Channel 2 | Separate control terminal; allows asynchronous or complementary switching of two power stages. |
| D2 | Drain of Channel 2 | Second power output node; pin-compatible with D1 for symmetrical PCB layout in H-bridge or dual-phase designs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual N-channel integration | Two matched 40 V/7.1 A MOSFETs in one SO-8 footprint-reduces board area by 40% vs. discrete dual-SOIC solution. |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS power supplies without derating. |
| Low Qrr body diode | 5.1 nC reverse recovery charge minimizes shoot-through risk and reduces snubber losses in synchronous rectification. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900 ppm Br+Cl, <1000 ppm Sb) compliant with IEC 61249-2-21. |
Applications
| Motor Control | DC-DC Converters |

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 |
|---|---|---|---|
| DMN4027LSD-13 | Same die, thinner SO-8 package (1.2 mm height vs. 1.75 mm); identical RDS(on), Qg, and thermal specs. | Preferred for ultra-low-profile assemblies where Z-height < 1.3 mm is mandatory. | Select when mechanical clearance constraints outweigh thermal margin needs. |
| SI4942DY-T1-GE3 | 40 V, 7.5 A, RDS(on) = 22 mΩ @ 10 V; higher Qg (15.5 nC); not AEC-Q101 qualified. | Acceptable for industrial DC-DC where automotive qualification is unnecessary. | Choose only if lower RDS(on) justifies higher gate drive power and absence of automotive stress testing. |
Compared with DMN4027SSD-13, DMN4027LSD-13 offers identical electrical performance in reduced height, while SI4942DY-T1-GE3 trades AEC-Q101 compliance for marginally lower conduction loss-making the former ideal for space-constrained automotive modules and the latter suitable for cost-sensitive industrial power rails.

FAQ
What is the maximum junction temperature rating for DMN4027SSD-13?
The DMN4027SSD-13 has an operating junction temperature range of –55°C to +150°C. Its absolute maximum TJ is 150°C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. Derating curves in the datasheet specify power limits above 25°C ambient based on SO-8 mounting conditions and dual-die thermal coupling.
Can DMN4027SSD-13 be used in a synchronous buck converter's high-side position?
Yes-each channel supports high-side configuration when driven by a bootstrap or isolated gate driver. The 40 V VBRDSS and 1.0–3.0 V VGS(th) enable reliable operation with standard 12 V gate drive. However, the lack of integrated level-shifting requires external circuitry to maintain VGS > 10 V during high-side conduction.
Is the body diode in DMN4027SSD-13 suitable for reverse recovery in hard-switched topologies?
Yes-the body diode exhibits Qrr = 5.1 nC and trr = 12.1 ns under 2.1 A, 100 A/µs conditions, making it viable for synchronous rectification in 300–500 kHz buck converters. Its soft recovery characteristic reduces voltage overshoot and EMI compared to standard silicon diodes.
How does the SO-8 package's dual-die thermal design affect power derating?
When both channels operate simultaneously, RθJA drops to 58°C/W (vs. 70°C/W for single-die mode), increasing total dissipation limit to 2.14 W at 25°C ambient. But simultaneous full-load operation raises junction temperature faster-designers must apply the dual-die derating curve from page 2 of DS33040 Rev 2-2, not the single-channel table.
