Product details
Overview
DMN3025LFG-13 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in POWERDI3333-8 package, optimized for high-efficiency power management with 18 mΩ RDS(on) at VGS = 10 V, 7.5 A continuous drain current at 25°C, and AEC-Q101 qualification for automotive reliability. It serves as a main or synchronous rectifier switch in DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMN3025LFG-13 datasheet, DMN3025LFG-13 pinout, DMN3025LFG-13 application, or DMN3025LFG-13 equivalent, key selection criteria include RDS(on) at 4.5 V (28 mΩ), thermal resistance (RθJA = 61 °C/W), UIS ruggedness, and compact POWERDI3333-8 footprint enabling high-density board layouts.
Technical Context
This MOSFET employs planar silicon process technology to balance low on-resistance and fast switching performance. Its gate threshold voltage (0.8–2.0 V) supports logic-level drive from 3.3 V and 5 V controllers, while its 100% production-tested UIS capability ensures robustness against inductive transients in buck and boost topologies.
The device features low gate charge (Qg = 11.6 nC at VGS = 10 V) and fast switching times (tD(on) = 3.8 ns, tD(off) = 17.9 ns), minimizing conduction and switching losses in high-frequency (>500 kHz) power stages. Its thermally efficient POWERDI3333-8 package delivers RθJC = 6.4 °C/W for direct heatsinking via exposed drain pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 12 V/24 V automotive and industrial DC-DC inputs |
| RDS(on) @ VGS = 10 V | 18 mΩ - Enables ≤0.5 W conduction loss at 7.5 A, critical for thermally constrained PCBs |
| RDS(on) @ VGS = 4.5 V | 28 mΩ - Ensures usable on-state performance with standard 5 V microcontroller GPIO drive |
| ID (continuous, TA = 25°C) | 7.5 A - Supports medium-power loads such as 12 V → 3.3 V point-of-load converters |
| Qg (VGS = 10 V) | 11.6 nC - Reduces gate driver power demand and enables efficient operation above 1 MHz |
| RθJA | 61 °C/W - Allows 2.0 W dissipation at ambient without forced airflow on standard FR-4 |
| UIS Rating | 14 A / 10 mJ - Guarantees survival under worst-case inductive turn-off events in unregulated flyback or buck designs |
Pinout & Package
Package: POWERDI3333-8 - thermally enhanced surface-mount package with exposed drain paddle, 3.3 mm × 3.3 mm footprint, 0.8 mm height, and matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Common source connection for all four parallel internal cells; low-inductance return path for high di/dt currents |

| - (center pad) | Drain (D) | Internally connected to pins 5–8; must be soldered to large copper area for thermal and electrical performance |
| - | Gate (G) | No dedicated pin - gate connects internally to die; external gate signal routed to pin 1 via PCB trace (see schematic) |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | Same die, SO-8 package - higher RθJA (75 °C/W), larger footprint (5.0 × 6.0 mm) | Preferred where legacy SO-8 tooling exists or when higher peak power (PD = 2.5 W) is needed with heatsink | Select only if board rework for SO-8 is acceptable; otherwise DMN3025LFG-13 offers superior thermal density |
| DMT3006LPS-13 | 30 V, 6.5 A, 22 mΩ @ 4.5 V - lower ID but improved Ciss/Coss ratio for resonant LLC control | Better suited for ZVS/ZCS topologies requiring low Crss (42 pF vs 58 pF) and soft switching | Choose for high-frequency resonant converters; avoid for hard-switched buck where RDS(on) dominates loss |
Compared with DMN3025LSD-13, DMN3025LFG-13 reduces board area by 67% and improves thermal resistance by 19%, while DMT3006LPS-13 trades 1.6 A current capacity for lower gate-drain capacitance - making DMN3025LFG-13 optimal for space-constrained, medium-current hard-switched applications.

FAQ
What is the maximum junction temperature for continuous operation?
The DMN3025LFG-13 has a rated junction temperature range of −55°C to +150°C. For continuous operation, the absolute maximum TJ is +150°C. Derating begins at TA = +70°C, where continuous drain current drops to 6.1 A and power dissipation to 1.3 W, based on RθJA = 61 °C/W and standard FR-4 PCB layout per datasheet note 5.
Is the POWERDI3333-8 package compatible with standard reflow profiles?
Yes - the DMN3025LFG-13 is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1, meaning it can withstand unlimited floor life and standard Pb-free reflow profiles (peak 260°C, 10 s max). The matte tin finish meets MIL-STD-202 Method 208 for solderability, and the package's 0.8 mm profile avoids tombstoning on fine-pitch layouts.
Does this MOSFET require a gate resistor for stability?
A gate resistor (typically 5–22 Ω) is recommended to dampen ringing caused by PCB trace inductance interacting with the device's 1.5 Ω intrinsic gate resistance and 605 pF Ciss. While not mandatory for basic switching, omission risks EMI and shoot-through in half-bridge configurations; the datasheet's typical gate charge curve (Figure 11) assumes 1 Ω drive resistance.
Can the body diode be used for synchronous rectification?
The integrated body diode has VSD = 0.70–1.0 V at 6.3 A and trr = 5.5 ns, making it suitable for low-frequency freewheeling but not high-efficiency synchronous rectification above 200 kHz. For such applications, external Schottky or complementary MOSFETs are preferred; the device's low Qgd (2.4 nC) supports clean gate control when used as active switch only.
