Product details
Overview
DMG3407SSN-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SC59 package, rated for -30V VDSS, 50 mΩ RDS(ON) @ VGS = -10V, and -4.0A continuous drain current at TA = +25°C. It serves as a low-side load switch or synchronous rectifier in compact DC-DC converters.
For engineers reviewing the DMG3407SSN-7 datasheet, DMG3407SSN-7 pinout, DMG3407SSN-7 application, or DMG3407SSN-7 equivalent, key selection criteria include verified RDS(ON) at -4.5V gate drive, thermal resistance (RθJA = 98 °C/W under high-copper PCB conditions), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low on-resistance while maintaining fast switching speed (tD(ON) = 6.0 ns, tF = 30.7 ns) and low gate charge (Qg = 13.3 nC @ VGS = -10V). Its body diode exhibits VSD = -0.75 V @ IS = -1A and tRR = 8.5 ns, supporting efficient synchronous rectification.
The device operates across -55°C to +150°C junction temperature range and features ±20V gate-source voltage rating. Its SC59 package delivers 0.014 g mass and UL 94V-0 flammability compliance, with matte tin–annealed terminals meeting MIL-STD-202 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage before avalanche conduction in load-switch or high-side configuration |
| RDS(ON) | 50 mΩ @ VGS = -10V, ID = -4.1A - Enables <160 mW conduction loss at 4A load in 12V systems |
| ID (continuous) | -4.0 A @ TA = +25°C - Sustains full-rated current with FR-4 PCB and 2 oz copper thermal pad |
| Qg | 13.3 nC @ VGS = -10V - Reduces gate driver power demand and switching transition time in 500 kHz+ converters |
| RθJA | 98 °C/W (t<10s, 1"×1" 2 oz Cu) - Supports 1.1 W steady-state dissipation without active cooling in space-constrained layouts |
| VGS(TH) | -1.5 V (typ) - Ensures reliable turn-on with standard 3.3V or 5V logic-level gate drivers |
| Ciss | 582 pF - Limits Miller effect and enables stable operation with moderate gate resistance (Rg = 5 Ω) |
Pinout & Package
Package: SC59 - Surface-mount plastic package with 3-pin single-row configuration, 0.014 g mass, UL 94V-0 rated molding compound, and matte tin–annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Source (S) | Reference node for gate control and current return path | Connected to system ground or negative rail; ties directly to internal body diode cathode |
| Gate (G) | Control electrode for channel formation | Requires negative bias relative to source; low Ciss enables fast edge rates with minimal driver strength |
| Drain (D) | Current output terminal and high-voltage node | Handles full VDSS stress; connects to load or inductive node in buck converter low-side position |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at -4.5V | 72 mΩ - Enables direct interface with 5V microcontroller GPIO without level-shifting circuitry |
| Fast switching speed | tF = 30.7 ns - Minimizes dead-time losses in synchronous buck topologies operating above 300 kHz |
| AEC-Q101 qualified | Qualified for automotive powertrain and body electronics - supports extended temperature cycling and HTRB testing |
| Green packaging | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - Meets EU ELV and RoHS 2 directives for end-of-life recyclability |
| Low leakage | IDSS ≤ -1 μA @ VDS = -30V - Prevents standby power drain in always-on battery-powered modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET load-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | RDS(ON) = 30 mΩ @ -10V but only rated for -20V VDSS; higher Qg (22 nC) | Not suitable for 24V industrial systems or load-dump tolerant designs | Select when lower on-resistance is critical and voltage stress remains ≤20V |
| SI2307DS-T1-GE3 | RDS(ON) = 60 mΩ @ -4.5V; no AEC-Q101 qualification; RθJA = 150 °C/W (standard FR-4) | Limited to consumer-grade portable devices without automotive or industrial thermal constraints | Choose for cost-sensitive, non-automotive applications where gate drive is ≥-10V |
Compared with DMN3026LSD-13 and SI2307DS-T1-GE3, the DMG3407SSN-7 uniquely balances -30V robustness, -4.5V logic compatibility, AEC-Q101 qualification, and 98 °C/W thermal performance-making it optimal for space-constrained automotive and industrial power switches requiring both reliability and efficiency.

FAQ
Is DMG3407SSN-7 suitable for hot-swap applications?
Yes. With -30V VDSS, low RDS(ON), and fast turn-off (tF = 30.7 ns), it supports controlled inrush current limiting and reverse-current blocking in hot-swap circuits. Its AEC-Q101 qualification further validates robustness against voltage transients encountered during live insertion.
What is the maximum safe gate-source voltage for continuous operation?
The absolute maximum VGS is ±20V per the datasheet. For reliable long-term operation, gate drive should be limited to -12V maximum to avoid oxide stress, especially under temperature cycling. The typical VGS(TH) of -1.5V allows full enhancement with -4.5V to -10V logic-level signals.
Does DMG3407SSN-7 require a gate resistor for stability?
A gate resistor (Rg) of 3–10 Ω is recommended to dampen ringing caused by PCB trace inductance interacting with Ciss (582 pF) and Crss (76 pF). This prevents false turn-on due to dv/dt coupling and ensures clean switching edges in high-frequency DC-DC applications.
Can DMG3407SSN-7 replace an N-channel MOSFET in high-side switching?
No. As a P-channel device, it is inherently suited for low-side switching or high-side configurations where the source is tied to the positive rail. Replacing an N-channel high-side switch would require redesigning the gate drive to deliver negative voltage relative to source-making it unsuitable as a drop-in N-channel substitute.
