Product details
Overview
DMG4406LSS from Diodes Incorporated is an N-channel enhancement-mode MOSFET optimized for high-efficiency power management, featuring 30 V V(BR)DSS, 11 mΩ RDS(ON) @ 10 V VGS, and 10.3 A continuous drain current at 25°C - used in DC-DC converters, backlighting circuits, and load switching stages where low conduction loss and fast switching are critical.
For engineers reviewing the DMG4406LSS datasheet, DMG4406LSS pinout, DMG4406LSS application, or DMG4406LSS equivalent, this device supports high-current, low-voltage switching with AEC-Q101 qualification, SO-8 package thermal performance, and validated UIS ruggedness - key for automotive interior lighting and industrial power rail control.
Technical Context
This MOSFET employs a planar trench-gate structure to balance low RDS(ON) and controlled gate charge (26.7 nC @ 10 V), enabling efficient synchronous rectification and PWM-driven buck/boost stages. Its 125 pF Crss and 21.2 ns tr ensure minimal switching losses in 300–1000 kHz power topologies.
The device integrates a robust body diode with 8.5 ns trr and 7.0 nC Qrr, supporting discontinuous conduction mode (DCM) operation without external freewheeling diodes. Thermal resistance of 6.4 °C/W RθJC enables direct heatsinking in compact SO-8 layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 30 V - Maximum blocking voltage before avalanche onset; sets usable input range for 24 V nominal systems. |
| RDS(ON) max | 11 mΩ @ 10 V VGS - Enables ≤1.1 W conduction loss at 10 A, critical for thermally constrained PCBs. |
| ID max (TC = 25°C) | 10.3 A - Continuous current rating under standard SO-8 FR-4 mounting; defines safe operating area for steady-state loads. |
| Qg total | 26.7 nC @ 10 V - Determines gate drive power and switching speed; compatible with standard 1–2 A peak gate drivers. |
| EAS | 24 mJ - Avalanche energy rating confirms reliability under inductive turn-off stress in motor or solenoid drives. |
| RθJC | 6.4 °C/W - Junction-to-case thermal resistance allows direct thermal pad coupling to copper planes or small heatsinks. |
| UIS tested | 100% production-tested - Guarantees unclamped inductive switching capability without derating for transient overloads. |
Pinout & Package
Package: SO-8 surface-mount plastic package with matte tin-plated copper leadframe, UL 94V-0 rated molding compound, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Common source connection for all four internal die segments; low-inductance parallel path for return current. |
| 5, 6, 7, 8 | Drain (D) | Parallel-connected drain terminals forming main power output node; designed for high-current PCB copper pour routing. |
| G (pin 3 in internal schematic) | Gate (G) | Single gate terminal (pin 3 per marking diagram); low 1.2 Ω Rg minimizes gate oscillation risk with standard RC snubbing. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 4.5 V | 15 mΩ - Enables logic-level drive from 5 V microcontrollers without gate boosters in battery-powered systems. |
| Fast switching | tr = 21.2 ns, tf = 5.1 ns - Reduces transition losses in high-frequency DC-DC converters (>500 kHz). |
| AEC-Q101 qualified | Qualified for automotive interior modules - meets temperature cycling, HTRB, and ESD requirements for non-safety-critical ECUs. |
| Green construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); compliant with RoHS 2 and JESD22-A110. |
| SO-8 thermal layout | Optimized pad design (AP02001) achieves 61 °C/W RθJA with 1-inch² copper - simplifies thermal validation for industrial designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3016LSS | Higher RDS(ON): 16 mΩ @ 10 V; lower ID: 8.5 A; same SO-8 package. | Less suitable for >8 A continuous loads; higher conduction loss reduces efficiency in high-duty-cycle converters. | Select when cost sensitivity outweighs efficiency targets and peak current stays below 7 A. |
| NTMFS4C09NT1G | Lower RDS(ON): 7.5 mΩ @ 10 V; higher ID: 15.5 A; same SO-8 footprint but different pinout (source pins on opposite side). | Requires PCB redesign due to reversed source/drain pin mapping; better for high-current server VRMs. | Choose only if board revision allows pinout change and thermal margin must exceed 12 A. |
Compared with DMN3016LSS and NTMFS4C09NT1G, DMG4406LSS delivers optimal balance of conduction loss, switching speed, and drop-in compatibility in SO-8 - making it preferred for mid-power automotive and industrial DC-DC designs where layout reuse and AEC-Q101 compliance are mandatory.

FAQ
Is DMG4406LSS suitable for automotive under-hood applications?
No - while DMG4406LSS is AEC-Q101 qualified, its maximum junction temperature is 150°C and SO-8 package thermal resistance limits sustained operation above 105°C ambient. It is approved for interior cabin modules (e.g., lighting, infotainment) but not under-hood engine control units.
What is the recommended gate resistor value for 500 kHz switching?
A 3.3 Ω series gate resistor is recommended to dampen ringing while maintaining 21.2 ns rise time; this value balances EMI suppression and switching loss, verified with 12.5 nC Qgs and 1.2 Ω intrinsic Rg per datasheet Figure 11.
Does DMG4406LSS require a Schottky catch diode in synchronous buck topologies?
No - the integrated body diode has 8.5 ns trr and 7.0 nC Qrr, enabling reliable synchronous rectification down to 200 kHz without external diode; however, external Schottky may be added for ultra-low-noise audio applications.
Can DMG4406LSS replace SiC MOSFETs in 30 V systems?
No - SiC devices offer superior high-temperature switching and lower Qg, but DMG4406LSS is optimized for cost-sensitive 30 V silicon solutions where 15 mΩ @ 4.5 V drive and AEC-Q101 compliance are primary selection criteria, not wide-bandgap performance.
