Product details
Overview
DMG7401SFG-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for -30V VDSS, 13mΩ RDS(ON) @ VGS = -10V, and -9.8A continuous drain current at TA = +25°C. It delivers low conduction loss and fast switching for compact DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMG7401SFG-13 datasheet, DMG7401SFG-13 pinout, DMG7401SFG-13 application, or DMG7401SFG-13 equivalent, key selection criteria include verified RDS(ON) at -4.5V (-25mΩ), AEC-Q101 qualification, thermal resistance (RθJA = 60°C/W with 1-inch2 copper), body diode forward voltage (-0.7V typ), and gate charge (Qg = 41nC @ VGS = -10V).
Technical Context
This MOSFET employs trench-gate technology to achieve low RDS(ON) while maintaining robust avalanche capability (EAR = 104mJ) and controlled dynamic parameters (Ciss = 2246pF, Qgd = 8.0nC). Its negative threshold voltage (-1.7V to -3.0V) ensures reliable turn-on with standard logic-level gate drivers.
The PowerDI3333-8 package integrates three source terminals and dual drain leads to reduce parasitic inductance and improve current sharing. Thermal performance is optimized via direct die-to-pad thermal path (RθJC = 3.0°C/W), enabling high-power density operation without external heatsinking in transient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Withstands up to -30V drain-source blocking voltage before avalanche onset. |
| RDS(ON) @ VGS = -10V | 13mΩ max - Enables <125mW conduction loss at -9.8A, critical for high-efficiency buck stages. |
| RDS(ON) @ VGS = -4.5V | 25mΩ max - Supports 3.3V/5V gate drive in space-constrained power rails. |
| Qg @ VGS = -10V | 41–58nC - Determines gate driver power requirement and switching transition time in hard-switched topologies. |
| tF | 22–38ns - Fast fall time minimizes overlap loss during synchronous rectification. |
| VSD | -0.7V typ @ IS = -1A - Low body diode forward drop reduces reverse recovery losses in freewheeling paths. |
| EAR | 104mJ - Rated repetitive avalanche energy supports unclamped inductive switching in automotive load-dump scenarios. |
Pinout & Package
Package: PowerDI3333-8 - Thermally enhanced 8-pin surface-mount package with exposed drain paddle, 3.3mm × 3.3mm footprint, and 0.8mm height. Features three parallel source terminals (Pins 2, 4, 6) and dual drain connections (Pins 1, 8) for reduced package inductance and improved current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Drain | High-current output node; electrically tied internally to exposed thermal pad for low-inductance power return and heat dissipation. |
| 2, 4, 6 | Source | Common return path for load current; triple-source configuration lowers effective RDS(ON) and improves thermal spreading. |
| 3, 5, 7 | Gate | Control input; pins 3 and 5 are gate inputs, pin 7 is gate sense - enables Kelvin-connected gate drive for precise threshold control. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMP3018SFV | Lower RDS(ON) (1.8mΩ @ -10V), but larger SO-8 package and no AEC-Q101 rating. | Preferred for non-automotive, space-unconstrained designs where ultra-low conduction loss dominates. | Select DMP3018SFV only if board area > 30mm² is available and automotive qualification is unnecessary. |
| DMG1012T | Smaller PowerDI3333-8 footprint, but lower VDSS (-20V) and higher RDS(ON) (32mΩ @ -4.5V). | Suitable for 3.3V/5V logic-level loads only; not viable for 12V automotive or 24V industrial rails. | Choose DMG1012T only for low-voltage, low-power applications where VDSS margin is ≥2× nominal rail. |
Compared with DMP3018SFV and DMG1012T, DMG7401SFG-13 uniquely balances AEC-Q101 compliance, -30V rating, and 25mΩ RDS(ON) at -4.5V in the smallest qualified footprint-making it optimal for automotive-grade, space-constrained power switches where reliability and density are co-prioritized.

FAQ
What is the maximum continuous drain current for DMG7401SFG-13 at 70°C ambient?
The maximum continuous drain current is -7.7A at TA = +70°C with standard FR-4 PCB layout (2oz copper, minimum pad), and -10.8A when mounted on a 1-inch² copper plate. These values reflect thermal derating due to junction-to-ambient resistance (RθJA = 60°C/W with enhanced copper).
Is DMG7401SFG-13 suitable for synchronous rectification in a 500kHz buck converter?
Yes - its 22–38ns fall time, 8.0nC gate-drain charge, and 352pF output capacitance support efficient synchronous rectification at 500kHz. The low QRR (9.5–18nC) further reduces switching loss during body-diode commutation.
Does DMG7401SFG-13 require a gate resistor for stability in high-speed switching?
A gate resistor (typically 3–10Ω) is recommended to dampen ringing caused by gate loop inductance and prevent spurious turn-on. The datasheet specifies tD(ON) and tD(OFF) test conditions using RG = 3Ω, confirming this value provides optimal trade-off between speed and oscillation suppression.
How does the PowerDI3333-8 package improve thermal performance over SO-8?
PowerDI3333-8 achieves RθJA = 60°C/W (vs. ~100°C/W for SO-8) via direct die-to-PCB thermal path through an exposed drain paddle. Its 3.3mm × 3.3mm footprint also allows tighter copper pour under the device, reducing thermal resistance by >40% compared to SO-8 on identical board layouts.
