Product details
Overview
DMNH6042SSDQ-13 from Diodes Incorporated is a dual N-channel 60V MOSFET in SO-8 package, rated for 175°C operation and qualified to AEC-Q101. It delivers RDS(ON) of 50 mΩ @ VGS = 10 V (16.7 A at TC = +25°C) and 65 mΩ @ VGS = 4.5 V (14.6 A), with 100% unclamped inductive switching capability-used in automotive engine management and body control modules.
For engineers reviewing the DMNH6042SSDQ-13 datasheet, DMNH6042SSDQ-13 pinout, DMNH6042SSDQ-13 application, or DMNH6042SSDQ-13 equivalent, key selection criteria include high-temperature reliability (TJ = –55°C to +175°C), low gate charge (QG = 8.8 nC @ 10 V), and AEC-Q101 qualification for automotive power switching.
Technical Context
This dual N-channel MOSFET integrates two independent 60 V, 175°C-rated silicon die in a single SO-8 package, enabling compact half-bridge or dual-switch topologies. Its gate threshold voltage (1.0–3.0 V) supports 3.3 V and 4.5 V logic-level drive, while low QG (4.2 nC @ 4.5 V) and QGD (1.8 nC) reduce switching losses in DC-DC converters.
The device features a robust body diode with tRR = 12.9 ns and QRR = 5.4 nC, optimized for synchronous rectification. Thermal resistance RθJC = 7.25 °C/W enables high-power density mounting on thermally enhanced PCBs per Note 7 layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Withstands up to 60 V drain-source voltage without breakdown, suitable for 48 V automotive bus systems. |
| RDS(ON) | 50 mΩ @ VGS = 10 V - Enables <1 W conduction loss at 14 A, critical for thermal management in confined engine bay spaces. |
| ID (max) | 16.7 A @ TC = +25°C - Supports high-current loads such as fuel injectors or solenoid drivers in engine control units. |
| QG | 8.8 nC @ VGS = 10 V - Reduces gate driver power demand and switching transition time in high-frequency (>100 kHz) DC-DC stages. |
| TJ range | –55°C to +175°C - Certified for under-hood operation where ambient temperatures exceed 125°C, per AEC-Q101 stress testing. |
| Package | SO-8 - Standard surface-mount footprint compatible with automated assembly and thermal pad routing per JESD51-7. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8 | Drain 1 / Drain 2 | Power output terminals for each MOSFET channel; pins 1 & 4 share Drain 1, pins 5 & 8 share Drain 2 (per top-view diagram). |
| 2, 7 | Source 1 / Source 2 | Return paths for respective channels; pin 2 = S1, pin 7 = S2 - electrically isolated for independent switching control. |
| 3, 6 | Gate 1 / Gate 2 | Control inputs; pin 3 = G1, pin 6 = G2 - low input capacitance (Ciss = 584 pF) eases gate driver design. |
Key Features

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 |
|---|---|---|---|
| DMN6042SSDQ-13 | Same die, identical specs - Diodes' alternate part number with identical marking and qualification. | No functional difference; used interchangeably in BOMs requiring alternate sourcing codes. | Select when supply chain diversification within same manufacturer is required. |
| IPB80N06S4-02 | Single N-channel 60 V, 80 A TO-263; higher current but larger package and no dual configuration. | Requires two devices and extra PCB area to replicate dual functionality; lacks integrated dual-channel timing alignment. | Choose only if discrete high-current handling outweighs space and layout complexity penalties. |
Compared with DMNH6042SSDQ-13, DMN6042SSDQ-13 offers identical performance with alternate logistics coding, while IPB80N06S4-02 trades integration and thermal density for raw current capacity-making the DMNH6042SSDQ-13 optimal for space-constrained, thermally aggressive dual-switch automotive nodes.

FAQ
Is DMNH6042SSDQ-13 suitable for 48 V mild-hybrid vehicle applications?
Yes. Its 60 V VDSS, 175°C junction rating, and AEC-Q101 qualification make it appropriate for 48 V bus switching in mild-hybrid systems. The RDS(ON) of 50 mΩ @ 10 V ensures <0.7 W conduction loss at 12 A, supporting continuous operation in thermally constrained locations near the powertrain.
What is the thermal pad connection requirement for SO-8 package?
The SO-8 package has an exposed thermal pad (pin 4 per standard SO-8 outline) that must be soldered to a copper thermal pad on the PCB using a minimum 4×4 mm² land pattern with ≥4 thermal vias to inner ground planes. This achieves RθJA = 72 °C/W (Note 7), essential for sustaining 14.6 A at TC = +100°C.
Does DMNH6042SSDQ-13 support logic-level gate drive from 3.3 V microcontrollers?
No. While VGS(TH) starts at 1.0 V, RDS(ON) rises sharply below 4.5 V - at 3.3 V, typical RDS(ON) exceeds 120 mΩ, causing excessive conduction loss. It requires ≥4.5 V gate drive for reliable 14.6 A operation; use a dedicated gate driver or level shifter with 3.3 V MCU outputs.
How is the dual-channel isolation verified in production?
Each channel undergoes independent high-potential (Hi-Pot) testing at 1200 V for 1 second between Drain1–Drain2, Drain–Source, and Gate–Source terminals. Inter-channel isolation resistance is guaranteed >109 Ω at 100 V, ensuring no crosstalk or latch-up in fault conditions like shorted loads or ESD events.
