Product details
Overview
DMNH4026SSD-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 40V VDSS, 24 mΩ RDS(ON) @ 10V VGS, and 7.5A continuous drain current at +25°C. It features AEC-Q101 qualification, 100% unclamped inductive switching rating, and operation up to +175°C junction temperature-designed for motor control, backlighting, and DC-DC converter power stages.
For engineers reviewing the DMNH4026SSD-13 datasheet, DMNH4026SSD-13 pinout, DMNH4026SSD-13 application, or DMNH4026SSD-13 equivalent, key selection criteria include dual-channel thermal robustness, low RDS(ON) at 4.5V gate drive, SO-8 footprint compatibility, and automotive-grade reliability validation per AEC-Q101.
Technical Context
This dual MOSFET integrates two independent N-channel devices in a single SO-8 package with shared source terminals (S1/S2) and isolated gates (G1/G2), enabling half-bridge or synchronous buck configurations without external isolation. Its 10.5°C/W RθJC and 74°C/W RθJA (with thermal pad) support high-power density layouts in constrained spaces.
The device delivers fast switching (tD(ON) = 5.3 ns, tF = 4.8 ns) and low dynamic losses via 8.8 nC total gate charge at 4.5V and 19.1 nC at 10V, while maintaining low Ciss (1060 pF) and Crss (58 pF) for stable PWM operation in 300–1000 kHz DC-DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage for each channel in off-state; supports 24V system rails with margin. |
| RDS(ON) @ 10V | 24 mΩ max - Enables ≤1.8W conduction loss at 7.5A, critical for thermally limited motor drivers. |
| RDS(ON) @ 4.5V | 32 mΩ max - Ensures usable on-resistance with 5V logic-level gate drive in embedded controllers. |
| ID (TA=25°C) | 7.5 A - Continuous current per channel under standard FR-4 board conditions with 2oz copper. |
| TJ Range | −55°C to +175°C - Validated operation in under-hood automotive, industrial motor enclosures, and LED driver housings. |
| Qg @ 10V | 19.1 nC - Gate charge value defining driver strength requirement for <100 ns switching transitions. |
| EAS | 18 mJ - Avalanche energy rating confirming ruggedness against inductive kickback in relay/motor snubbing. |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin small-outline integrated circuit), molded green plastic, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Gate of Channel 1 | Independent control input for first N-channel MOSFET; requires dedicated gate resistor and driver path. |
| 2 (S1) | Source of Channel 1 | Common source node for Channel 1; electrically isolated from S2 but often tied externally in half-bridge topologies. |
| 3 (D1) | Drain of Channel 1 | High-side switch output node; connects to load or inductor in buck/boost configurations. |
| 4 (D2) | Drain of Channel 2 | Second high-side or low-side switch node; enables dual-switch topologies without discrete packaging. |
| 5 (G2) | Gate of Channel 2 | Independent gate terminal for second MOSFET; supports asynchronous or complementary PWM control. |
| 6 (S2) | Source of Channel 2 | Source node for Channel 2; may be connected to ground (low-side) or floating (high-side) depending on layout. |
| 7, 8 (D1/D2) | Drain Power Pads | Exposed drain terminals (pins 7 & 8) are internally connected to D1 and D2 respectively; used for thermal dissipation and current carrying. |
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 |
|---|---|---|---|
| DMN6016LSD-13 | 60V VDSS, 16mΩ @ 10V, SO-8, single-channel (not dual) | Requires two units for dual functionality; higher voltage headroom but larger footprint and gate drive complexity | Select when 60V blocking is mandatory and layout allows duplication; not drop-in compatible |
| SI6926ADQ-T1-GE3 | 30V VDSS, 22mΩ @ 10V, SO-8 dual N-channel, no AEC-Q101 qualification | Lacks automotive reliability validation; unsuitable for under-hood use despite matching pinout | Acceptable for consumer-grade DC-DC where temperature and qualification requirements are relaxed |
Compared with DMNH4026SSD-13, DMN6016LSD-13 offers higher voltage tolerance but doubles component count and gate drive overhead, while SI6926ADQ-T1-GE3 matches pinout and RDS(ON) but omits AEC-Q101 validation and 175°C operation-making DMNH4026SSD-13 the sole choice for thermally demanding automotive power stages.

FAQ
What is the maximum continuous drain current per channel at +100°C ambient?
The DMNH4026SSD-13 supports 5.3A continuous drain current per channel at TA = +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits under standard FR-4 board conditions with 2oz copper and no forced airflow.
Does this part support 3.3V logic-level gate drive?
No-VGS(TH) ranges from 1V to 3V, but RDS(ON) is only guaranteed at VGS ≥ 4.5V (32 mΩ max). At 3.3V, conduction resistance rises significantly (>60 mΩ), increasing power loss and thermal stress beyond safe operation.
How is the SO-8 package thermally enhanced in this device?
The SO-8 package uses exposed drain pads (pins 7 and 8) connected internally to D1 and D2, providing low-impedance thermal paths to the PCB. With 2oz copper and a 1-inch square thermal pad, RθJA improves from 101°C/W to 74°C/W, enabling 2.0W power dissipation.
Is there a pin-compatible automotive variant with extended qualification?
Yes-the DMNH4026SSDQ is the AEC-Q101 qualified automotive variant, identical in pinout, electrical specs, and package. It differs only in traceability, test documentation, and part marking (Q suffix), and is intended for production automotive applications requiring PPAP compliance.
