Product details
Overview
DMN4026SSD-13 from Diodes Incorporated is a 40V dual N-channel enhancement-mode MOSFET in SO-8 package, featuring 24 mΩ RDS(ON) @ VGS = 10V, 9.0 A continuous drain current at TA = +25°C, and fast switching with 5.3 ns turn-on delay. It serves as a high-efficiency synchronous rectifier or half-bridge switch in DC-DC converters.
For engineers reviewing the DMN4026SSD-13 datasheet, DMN4026SSD-13 pinout, DMN4026SSD-13 application, or DMN4026SSD-13 equivalent, key selection criteria include dual-channel RDS(ON) matching at 4.5V/10V drive, SO-8 thermal performance (RθJA = 71°C/W), body diode recovery (trr = 10.5 ns), and automotive-grade packaging compliance.
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single SO-8 footprint, enabling compact half-bridge or dual-switch topologies without cross-conduction risk when driven with complementary gate signals. Its low gate charge (Qg = 19.1 nC @ 10V) and low Ciss (1060 pF) support high-frequency operation up to 1 MHz in buck converters.
The device operates across –55°C to +150°C junction temperature, with gate threshold voltage tightly specified (1–3 V), and exhibits stable RDS(ON) over temperature-20 mΩ @ 4.5V/5A up to +125°C-enabling reliable performance in thermally constrained motor control PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage for 12V/24V bus-level power stages |
| RDS(ON) @ 10V | 24 mΩ max - Enables ≤0.22 W conduction loss at 9A in high-side switch |
| RDS(ON) @ 4.5V | 32 mΩ max - Supports logic-level drive from 3.3V/5V microcontrollers |
| ID (continuous) | 7.0 A @ TA = +25°C - Sustains 7W dissipation with standard FR-4 layout |
| Qg @ 10V | 19.1 nC typ - Reduces gate driver power demand in 500 kHz+ switching |

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 |
|---|---|---|---|
| DMN4026LSD-13 | Same die, but lead-free matte tin finish on gull-wing leads instead of SO-8; identical RDS(ON), Qg, and thermal specs | Designed for wave soldering; lacks SO-8's optimized thermal pad layout for high-power density | Select for legacy through-hole compatible assembly or where SO-8 reflow profile constraints exist |
| SI4532DY-T1-GE3 | Higher RDS(ON) (30 mΩ @ 10V), larger Qg (28 nC), and higher RθJA (85°C/W); same SO-8 footprint | Lower switching efficiency in >300 kHz applications; requires larger gate drivers due to higher Qg | Acceptable for cost-sensitive 100–200 kHz DC-DC where thermal headroom exceeds 15°C |
Compared with DMN4026SSD-13, DMN4026LSD-13 offers identical electrical performance but different assembly compatibility, while SI4532DY-T1-GE3 trades 25% higher conduction loss and slower switching for broader distributor availability-making DMN4026SSD-13 optimal for thermally constrained, high-frequency power stages.

FAQ
What is the maximum safe operating junction temperature for DMN4026SSD-13?
The absolute maximum junction temperature is +150°C, validated per JEDEC JESD22-A104. Operation above +135°C requires derating of continuous current to maintain reliability; thermal design must ensure RθJA × PD + TA ≤ 135°C for long-term stability in industrial environments.
Can DMN4026SSD-13 be used in automotive applications?
DMN4026SSD-13 is not AEC-Q101 qualified; Diodes offers the pin-compatible DMN4026SSDQ-13 variant for automotive use, which undergoes stress testing per AEC-Q101 Rev D and is manufactured in IATF 16949-certified facilities with PPAP documentation support.
How does the SO-8 package's thermal performance compare between steady-state and pulsed conditions?
In steady-state operation on FR-4 with 1-inch² copper, RθJA is 71°C/W; for short pulses (<10 ms), transient thermal resistance drops to 43°C/W, allowing 70 A pulsed drain current (IDM) without exceeding TJMAX, provided duty cycle remains ≤1%.
Is the body diode suitable for synchronous rectification without external control?
No-the internal body diode conducts only during dead-time intervals; synchronous rectification requires active gate control of both channels using complementary PWM signals with precise dead-time insertion to prevent shoot-through, as confirmed in Diodes' AN-2001 application note.
