Product details
Overview
DMG7401SFGQ-7 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 delivers low on-resistance with fast switching for high-efficiency DC-DC converters and backlighting power stages.
For engineers reviewing the DMG7401SFGQ-7 datasheet, DMG7401SFGQ-7 pinout, DMG7401SFGQ-7 application, or DMG7401SFGQ-7 equivalent, key selection criteria include gate threshold voltage (-1.7 to -3.0V), thermal resistance (RθJA = 60°C/W with 1-inch copper), body diode recovery (trr = 20–31ns), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET employs trench-gate silicon technology optimized for low RDS(ON) while maintaining controlled gate charge (Qg = 41–58nC @ VGS = -10V) and fast switching transitions (tD(on) = 11.3–23ns). Its symmetric dual-source/dual-drain layout supports high-current bidirectional conduction paths in synchronous buck topologies.
The device integrates ESD protection on gate terminals and features a thermally enhanced POWERDI®3333-8 package with 3.0°C/W RθJC. Its body diode exhibits low forward voltage (VSD = -0.7 to -1.0V @ IS = -1A) and tightly specified reverse recovery charge (Qrr = 9.5–18nC), enabling efficient freewheeling in hard-switched converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -30V - Ensures safe operation in 24V automotive and industrial bus systems with margin against transients. |
| RDS(ON) Max | 13mΩ @ VGS = -10V - Limits conduction loss to ≤1.3W at 10A, critical for thermally constrained DC-DC phases. |
| ID Max (TA=25°C) | -9.8A - Supports compact 10A-class power stages without external heatsinking under standard PCB layout. |
| Qg Total | 41–58nC @ VGS = -10V - Enables efficient gate drive with <1W driver loss at 500kHz switching frequency. |
| trr / Qrr | 20–31ns / 9.5–18nC - Reduces switching loss and EMI in synchronous rectification by minimizing reverse recovery tail. |
| RθJA | 60°C/W (with 1-inch copper) - Allows 2.2W continuous dissipation at +70°C ambient, suitable for sealed enclosures. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive power management including temperature cycling and HTRB. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | RDS(ON) = 26mΩ @ -4.5V; SO-8 package; RθJA = 62°C/W | Larger footprint; lower thermal performance; no AEC-Q101 rating | Acceptable for cost-sensitive industrial non-automotive designs where board space and qualification are not constraints. |
| SIR178DP-T1-GE3 | RDS(ON) = 11.5mΩ @ -10V; PowerPAK® 3.3×3.3; RθJA = 55°C/W | Same footprint but higher gate charge (Qg = 62nC); no AEC-Q101 documentation found | Better conduction loss, but requires stronger gate driver; verify qualification status before automotive use. |
Compared with DMG7401SFGQ-7, DMN3026LSD-13 trades thermal performance and qualification for lower cost, while SIR178DP-T1-GE3 offers marginally lower RDS(ON) but lacks documented AEC-Q101 compliance-making DMG7401SFGQ-7 the only fully qualified, thermally optimized choice for automotive power switching.

FAQ
What is the maximum continuous drain current at 100°C ambient?
At TA = +100°C, the DMG7401SFGQ-7 supports -5.2A continuous drain current when mounted on FR-4 with 1-inch square copper (Note 7). This is derived from its 1.3W PD rating at +70°C and thermal derating slope of -15.4mW/°C above that point, validated per JEDEC JESD51-1.
Can this MOSFET be used in a synchronous buck high-side configuration?
No - DMG7401SFGQ-7 is a P-channel device intended for high-side switching, but its -30V V(BR)DSS and gate threshold range (-1.7 to -3.0V) make it unsuitable for bootstrap-driven high-side N-MOSFET replacement. It functions as a self-contained high-side switch with logic-level gate drive, not as a synchronous rectifier in low-side positions.
Does the POWERDI®3333-8 package require solder paste stencil adjustments?
Yes - the exposed drain pad (pins 1–4) requires a 70–80% aperture ratio on the stencil to ensure robust thermal vias and mechanical adhesion. Diodes' AP02001 recommends 0.42mm × 0.42mm solder pads with eight 0.3mm thermal vias spaced evenly under the pad, filled with conductive epoxy for production-grade thermal performance.
Is the body diode suitable for reverse polarity protection?
Yes - the integrated body diode has a rated forward current of -3.0A and VSD = -0.7 to -1.0V at -1A, making it suitable for basic reverse polarity protection in low-power 24V systems. However, its 20–31ns trr limits use in high-frequency reverse-battery scenarios where fast recovery is required to avoid latch-up.
