Product details
Overview
DMG4468LFG from Diodes Incorporated is an N-channel enhancement-mode MOSFET in a DFN3030-8 package, rated for 30 V VDSS, 7.62 A continuous drain current at 25°C, and 10 mΩ typical RDS(on) at VGS = 10 V. It delivers low input capacitance (867 pF), fast switching (tD(on) = 5.46 ns), and AEC-Q101 qualification for automotive power management.
For engineers reviewing the DMG4468LFG datasheet, DMG4468LFG pinout, DMG4468LFG application, or DMG4468LFG equivalent, key selection criteria include its 30 V rating, 10 mΩ RDS(on) at 10 V gate drive, DFN3030-8 thermal performance (RθJA = 126.7°C/W), and AEC-Q101 compliance for under-hood DC-DC and load switch use cases.
Technical Context
This MOSFET operates as a high-efficiency, low-voltage power switch with gate threshold voltage of 1.0–2.0 V and guaranteed turn-on at 4.5 V. Its internal structure supports synchronous rectification and reverse-biased body diode conduction (VSD = 0.7–1.0 V at 1 A).
Thermal design relies on its DFN3030-8 footprint with exposed thermal pad and FR-4 PCB mounting per minimum pad layout. Junction-to-ambient thermal resistance is 126.7°C/W under standard conditions, enabling 0.99 W steady-state dissipation at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage before avalanche; suitable for 24 V automotive systems with margin. |
| RDS(on) @ VGS = 10 V | 10 mΩ typ - Enables <100 mW conduction loss at 10 A, critical for high-current load switches. |
| Ciss | 867 pF - Low input capacitance reduces gate drive power and speeds up switching transitions. |
| tD(on) | 5.46 ns - Short delay time supports >10 MHz PWM operation in compact DC-DC converters. |
| PD | 0.99 W - Power dissipation limit at TA = 25°C with recommended PCB layout. |
| TJ Range | −55 to +150°C - Full operational range meets AEC-Q101 requirements for engine compartment placement. |

Applications
| Automotive Load Switch | DC-DC Synchronous Rectifier |
|---|---|

IC Role / Device Role / Timing Role: High-side load switch controlling 12–24 V rail delivery with fast fault response. Use Value: 10 mΩ RDS(on) limits voltage drop to <100 mV at 10 A, preserving system efficiency and thermal headroom. |
Use Scenario: Secondary-side rectification in 30 V input buck converters for ADAS camera power supplies. IC Role / Device Role / Timing Role: Synchronous rectifier replacing Schottky diode to minimize conduction loss. Use Value: 0.7 V VSD and low Qgd (6.15 nC) enable high duty-cycle operation with minimal reverse recovery loss. |

IC Role / Device Role / Timing Role: Fast-turning low-side MOSFET in half-bridge topology with precise dead-time control. Use Value: 5.46 ns tD(on) and 14.53 ns tr ensure tight timing margins and reduced shoot-through risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LFG | Higher RDS(on) (25 mΩ @ 10 V), same DFN3030-8 package and 30 V rating. | Lower current handling (5.5 A ID) limits use in >6 A load switches. | Select when lower cost is prioritized over conduction loss in <5 A applications. |
| Si2302DS | Lower VDSS (20 V), higher RDS(on) (45 mΩ @ 4.5 V), same 8-pin DFN footprint. | Not suitable for 24 V automotive systems due to insufficient voltage margin. | Choose only for 5 V–12 V logic-level applications where 30 V rating is unnecessary. |
Compared with DMG4468LFG, DMN3025LFG trades conduction efficiency for cost in mid-current loads, while Si2302DS sacrifices voltage rating and on-resistance for legacy compatibility-neither matches the combination of 30 V, sub-15 mΩ, and AEC-Q101 validation.

FAQ
What is the maximum continuous drain current at 85°C ambient?
The DMG4468LFG supports 4.83 A continuous drain current at TA = 85°C with device mounted on FR-4 PCB using the minimum recommended pad layout. This derating reflects thermal limitations imposed by its 126.7°C/W junction-to-ambient resistance and 150°C maximum junction temperature.
Is the body diode rated for continuous reverse conduction?
Yes-the integrated body diode has a forward voltage of 0.7–1.0 V at 1 A and is characterized for continuous conduction in synchronous rectifier topologies. Its reverse recovery charge (Qrr) is not specified in the datasheet, but low Qgd (6.15 nC) and fast tf (6.01 ns) indicate optimized recovery behavior.
Does the DFN3030-8 package require solder paste stencil adjustments?
Yes-the DFN3030-8 package uses an exposed thermal pad centered on the bottom side. The recommended stencil design includes a 70–80% area ratio aperture for the thermal pad and standard 1:1 openings for perimeter pins to ensure void-free reflow and mechanical reliability.
Can DMG4468LFG be used in linear regulator applications?
No-it is not characterized or rated for linear mode operation. The Safe Operating Area (SOA) curve is not provided, and its RDS(on) temperature coefficient and thermal resistance make it unsuitable for sustained linear regulation; it is optimized for switched-mode operation only.
