Product details
Overview
DMG7401SFGQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in POWERDI®3333-8 package, rated for -30V V(BR)DSS, 13mΩ RDS(ON) @ VGS = -10V, and -9.8A continuous drain current at TA = +25°C. It integrates gate protection diodes and is AEC-Q101 qualified for automotive power management.
For engineers reviewing the DMG7401SFGQ-13 datasheet, DMG7401SFGQ-13 pinout, DMG7401SFGQ-13 application, or DMG7401SFGQ-13 equivalent, key selection criteria include low RDS(ON) at -4.5V gate drive, thermally efficient 3333 footprint, body diode recovery time (trr = 20–31ns), and AEC-Q101 qualification for automotive DC-DC converters.
Technical Context
This MOSFET employs trench-gate technology to achieve low on-resistance while maintaining fast switching performance. Its gate threshold voltage (VGS(th) = -1.7 to -3.0V) ensures reliable turn-on with standard logic-level drivers, and its low Crss (294–391pF) minimizes Miller effect during high-speed switching.
The device features an integrated body diode with VSD = -0.7 to -1.0V at IS = -1A and Qrr = 9.5–18nC, enabling efficient synchronous rectification in buck converters. Thermal resistance RθJC = 3.0°C/W supports high-power density layouts when mounted on copper thermal pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -30V - Ensures safe operation in 24V automotive and industrial bus systems with margin. |
| RDS(ON) | 13mΩ @ VGS = -10V - Delivers <0.5W conduction loss at 7A, critical for high-efficiency DC-DC stages. |
| ID (Continuous) | -9.8A @ TA = +25°C - Supports compact load switches and backlight LED drivers without forced cooling. |
| Qg | 41–58nC @ VGS = -10V - Enables <100ns switching transitions with 3Ω gate resistor, reducing dynamic losses. |
| trr | 20–31ns - Limits reverse recovery energy in synchronous rectifiers, improving light-load efficiency. |
| RθJA | 60°C/W (with 1-inch² copper) - Allows 2.2W dissipation at +70°C ambient, suitable for sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1012UW-7 | Smaller 1.0×0.6mm X1-WLBGA package; RDS(ON) = 28mΩ @ -4.5V; lower ID = -3.5A. | Better suited for ultra-compact wearables; insufficient current handling for automotive backlighting. | Select when board area is constrained below 1mm² and peak load ≤3.5A. |
| SI3457DV-T1-GE3 | SO-8 package; RDS(ON) = 20mΩ @ -4.5V; no AEC-Q101 qualification; higher RθJA = 90°C/W. | Acceptable for industrial non-automotive DC-DC, but lacks PPAP support and thermal performance. | Select only for cost-sensitive non-automotive designs where qualification and thermal margin are secondary. |
Compared with DMG7401SFGQ-13, DMG1012UW-7 trades current capacity and thermal robustness for extreme miniaturization, while SI3457DV-T1-GE3 sacrifices automotive qualification and thermal efficiency for legacy SO-8 compatibility and lower unit cost.

FAQ
What is the maximum gate-source voltage rating for DMG7401SFGQ-13?
The absolute maximum gate-source voltage (VGSS) is ±25V. Exceeding this rating risks permanent gate oxide damage. The device includes integrated gate protection diodes that clamp transient spikes within this range, making external TVS components unnecessary in most automotive load-switch applications.
Can DMG7401SFGQ-13 operate reliably at 85°C ambient temperature?
Yes - with a 1-inch² copper thermal pad, it delivers 1.3W continuous power at TA = +70°C and maintains safe junction temperature (TJ ≤ +150°C) up to +85°C ambient when derated per its RθJA = 60°C/W curve. Derating to 1.0W is recommended for sustained +85°C operation in sealed enclosures.
Is the POWERDI3333-8 package lead-free and RoHS compliant?
Yes - DMG7401SFGQ-13 uses matte tin annealed over copper leadframe and green molding compound compliant with EU Directive 2011/65/EU (RoHS 2). It contains <900ppm bromine, <900ppm chlorine, and <1000ppm antimony, satisfying Diodes' "Green" product definition.
Does DMG7401SFGQ-13 require a gate resistor for driving with a 3.3V MCU?
A gate resistor is recommended - typically 10Ω–47Ω - to dampen ringing caused by PCB trace inductance and prevent oscillation during turn-on/turn-off. While the gate threshold (VGS(th) = -1.7 to -3.0V) allows activation from 3.3V logic, uncontrolled edge rates increase EMI and dynamic losses; the resistor also protects the MCU output stage.
