Product details
Overview
DMN4034SSD-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 40V V(BR)DSS, 34mΩ RDS(on) at VGS = 10V and 6.3A continuous drain current, designed for high-efficiency DC-DC converters and motor control circuits where low conduction loss and fast switching are critical.
For engineers reviewing the DMN4034SSD-13 datasheet, DMN4034SSD-13 pinout, DMN4034SSD-13 application, or DMN4034SSD-13 equivalent, key selection criteria include verified RDS(on) at 4.5V (59mΩ), AEC-Q101 qualification, UIS ruggedness (27mJ), SO-8 thermal performance (RθJA = 58°C/W with two active die), and body diode recovery (trr = 11.2ns).
Technical Context
This dual MOSFET integrates two matched N-channel silicon die in a single SO-8 package, enabling half-bridge or synchronous rectifier topologies without inter-device mismatch. Its gate threshold voltage (1.0–3.0V) supports 3.3V and 5V logic-level drive, while Qg of 10–18nC at VGS = 10V ensures controllable turn-on/turn-off transitions.
The device features a robust body diode with VSD = 0.87–1.1V at IS = 6A and fast reverse recovery (Qrr = 4.8nC, trr = 11.2ns), making it suitable for synchronous buck stages where shoot-through immunity and diode conduction loss must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 40V - Maximum blocking voltage before avalanche onset; sets upper limit for input voltage in 24V industrial DC-DC designs. |
| RDS(on) | 34mΩ @ VGS = 10V - Conduction loss of 215mW at 6.3A; enables >95% efficiency in 12V→5V synchronous buck at 1MHz. |
| ID (continuous) | 6.3A @ TA = 25°C - Sustained current capability under standard PCB mounting; derates to 4.8A at 70°C ambient. |
| EAS | 27mJ - Single-pulse avalanche energy rating; allows safe operation during inductive load switching transients up to L = 100µH. |
| Qg | 10–18nC @ VGS = 10V - Total gate charge determines driver strength requirement; 18nC limits max switching frequency with 1Ω gate resistor to ~2MHz. |
| trr / Qrr | 11.2ns / 4.8nC - Fast body diode recovery reduces cross-conduction loss and EMI in synchronous rectification. |
| RθJA | 58°C/W (two active die) - Junction-to-ambient thermal resistance under full dual-die operation; defines heatsinking needs for 2.14W dissipation. |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin, 3.9mm × 4.9mm footprint per JEDEC MS-012, 1.27mm pitch). Molded green plastic case, matte tin-plated copper lead frame, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain 1 | High-side switch output node for first MOSFET; connects to input rail in high-side configuration. |
| S1 | Source 1 | Return path for first MOSFET; tied to common source node or ground in low-side layout. |
| G1 | Gate 1 | Control terminal for first MOSFET; requires ≥10V for full enhancement, compatible with 3.3V logic via gate driver. |
| S2 | Source 2 | Shared source connection between both MOSFETs in SO-8 dual configuration; electrically common to S1 in internal layout. |
| G2 | Gate 2 | Independent control terminal for second MOSFET; enables independent or complementary switching. |
| D2 | Drain 2 | Output node for second MOSFET; used for low-side switching or synchronous rectification leg. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| DMN4034LSD-13 | Same die, but lead-free matte tin finish only (no annealing); identical RDS(on), Qg, and thermal specs. | No functional difference; intended for RoHS-only (non-"Green") compliance requirements. | Select when "Green" policy (halogen-free) is not required and cost optimization is prioritized. |
| SI4942DY-T1-GE3 | 40V, 32mΩ @ 10V, but higher Qg (22nC) and no AEC-Q101 qualification; RθJA = 62°C/W. | Lacks automotive stress validation; unsuitable for under-hood use; higher gate drive loss at 1MHz+. | Choose only for non-automotive consumer applications where AEC-Q101 is unnecessary and lower RDS(on) outweighs gate charge penalty. |
Compared with DMN4034SSD-13, DMN4034LSD-13 offers identical electrical performance with simplified finish compliance, while SI4942DY-T1-GE3 trades AEC-Q101 ruggedness and lower Qg for marginally better conduction loss - making DMN4034SSD-13 optimal for automotive and industrial power stages demanding both reliability and efficiency.

FAQ
Is DMN4034SSD-13 pin-compatible with standard SO-8 dual MOSFETs?
Yes - DMN4034SSD-13 uses the industry-standard SO-8 outline (JEDEC MS-012) with 1.27mm pitch and identical pad layout. Pin assignments (D1/S1/G1/S2/G2/D2) match common dual-N-channel SO-8 footprints, enabling drop-in replacement in existing layouts without redesign.
What is the maximum operating junction temperature for DMN4034SSD-13?
The absolute maximum junction temperature is 150°C, as specified in the Thermal Characteristics table. Continuous operation at this temperature requires strict thermal management - with RθJA = 58°C/W (dual-die), ambient must be held ≤92°C to maintain TJ ≤150°C at 2.14W dissipation.
Does DMN4034SSD-13 support 3.3V logic-level gate drive?
Yes - its gate threshold voltage range (1.0–3.0V) and RDS(on) = 59mΩ at VGS = 4.5V confirm usable enhancement down to 3.3V. However, full 6.3A current requires VGS ≥ 10V; for 3.3V drive, expect ~3.5A ID with increased RDS(on), necessitating gate boosting or driver ICs for high-current operation.
How is the "Green" designation verified for DMN4034SSD-13?
"Green" status is certified per Diodes Incorporated's internal policy: zero halogens (Cl, Br), zero antimony compounds, and full RoHS compliance (Pb-free, Cd-free, etc.). This is confirmed by material declarations, UL 94V-0 flammability testing, and third-party lab reports - all documented in the DS32105 datasheet revision history and Diodes' website Green Policy portal.
