Product details
Overview
DMNH4026SSDQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET rated for 40V VDSS, 24 mΩ RDS(ON) @ 10V VGS, and 7.5A continuous drain current at +25°C, qualified to AEC-Q101 and rated for operation up to +175°C junction temperature. It is designed for automotive motor control, backlighting, and DC-DC converter power stages where high ambient temperature resilience and robust unclamped inductive switching are required.
For engineers reviewing the DMNH4026SSDQ-13 datasheet, DMNH4026SSDQ-13 pinout, DMNH4026SSDQ-13 application, or DMNH4026SSDQ-13 equivalent, key selection criteria include its dual SO-8 configuration, 100% UIS-rated ruggedness, low gate charge (19.1 nC @ 10V), thermal resistance of 74°C/W (with enhanced layout), and AEC-Q101 qualification with PPAP support.
Technical Context
This dual N-channel MOSFET integrates two matched silicon die in a single SO-8 package, enabling half-bridge or dual-switch topologies without inter-device mismatch. Its gate threshold voltage (1–3 V) supports 3.3V and 5V logic-level drive, while low Ciss (1060 pF) and fast switching (tr = 7.1 ns, tf = 4.8 ns) reduce switching losses in high-frequency DC-DC converters.
The device features fully isolated source terminals per channel, allowing independent source referencing-critical for high-side/low-side synchronous rectification. Its 100% unclamped inductive switching rating (IAS = 18 A, EAS = 18 mJ) and -55°C to +175°C operating range ensure reliability in under-hood automotive environments subject to thermal cycling and load dump transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BSC010N04LS6 | Lower RDS(ON) (1.0 mΩ), higher Qg (42 nC), same SO-8 package, AEC-Q101 qualified | Better conduction efficiency at >10A, but requires stronger gate driver and larger layout area for thermal management | Select when system prioritizes ultra-low conduction loss over gate drive simplicity and board space |
| Vishay SI7957DP-T1-GE3 | Higher RDS(ON) (32 mΩ @ 10V), lower Qg (12.5 nC), same SO-8, AEC-Q101 qualified | Better suited for low-duty-cycle, high-voltage transient suppression due to higher VDSS margin (45V) | Select when design emphasizes fast switching and transient robustness over steady-state efficiency |

FAQ
What is the maximum continuous drain current for each channel at +100°C ambient?
At TA = +100°C, the continuous drain current per channel is 5.3 A (derated from 7.5 A at +25°C), based on thermal limits defined by RθJA = 74°C/W and maximum TJ = +175°C. This value assumes use of the enhanced 2 oz copper PCB layout specified in the datasheet.
Is the exposed pad electrically isolated or connected internally?
The exposed pad (pins 7 and 8) is internally connected to both drain terminals (D1 and D2) and must be soldered to a common PCB copper pour serving as both thermal sink and electrical return path. It is not electrically isolated and must not be used as a signal reference.
Does DMNH4026SSDQ-13 support 3.3V logic-level gate drive?
Yes - with a gate threshold voltage range of 1.0–3.0 V and guaranteed RDS(ON) of 32 mΩ at VGS = 4.5 V, the device switches fully on using standard 3.3V microcontroller GPIO outputs, though 5V drive yields lower conduction loss (24 mΩ).
How is the 100% UIS rating validated and what does it cover?
The 100% UIS rating is verified per JEDEC JESD24-1 using L = 0.1 mH, IAS = 18 A, and EAS = 18 mJ. It confirms robustness against inductive energy stored in motor windings, solenoids, and relays without external protection, eliminating snubber design overhead.
