Product details
Overview
DMG7408SFG-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 7.0A continuous drain current at VGS = 10V, 23mΩ RDS(ON), and 100% production-tested UIS capability-designed for high-efficiency DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMG7408SFG-7 datasheet, DMG7408SFG-7 pinout, DMG7408SFG-7 application, or DMG7408SFG-7 equivalent, key selection criteria include RDS(ON) @ 4.5V (33mΩ), thermal resistance (RθJA = 63°C/W steady-state), avalanche energy (EAS = 12mJ), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET employs trench-gate silicon process to achieve low on-resistance while maintaining fast switching performance: tD(ON) = 2.9ns, tD(OFF) = 14.6ns, and Qg = 10.5nC @ VGS = 10V. Its integrated body diode supports synchronous rectification with VSD = 0.72V @ IS = 1A.
The device operates across –55°C to +150°C junction temperature range and features robust gate oxide integrity (VGSS = ±20V) and 100% production UIS testing (L = 0.3mH, TJ = +25°C), enabling reliable operation in transient-heavy power management circuits.

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 |
|---|---|---|---|
| DMN3025SFV | RDS(ON) = 25mΩ @ 10V; same PowerDI3333-8 package; lower Qg (8.5nC) | Better suited for ultra-high-frequency (>2MHz) DC-DC where gate charge dominates losses | Select when prioritizing switching loss over conduction loss in small-form-factor power supplies |
| DMT6009LPS | RDS(ON) = 9.5mΩ @ 10V; larger PowerSO-8 package; higher thermal mass (RθJA = 50°C/W) | Preferred for high-current (>10A), lower-frequency (<500kHz) industrial power stages | Choose when board space allows larger footprint and thermal design targets <1.5W dissipation |
Compared with DMN3025SFV and DMT6009LPS, DMG7408SFG-7 delivers optimal balance of low RDS(ON), moderate Qg, and AEC-Q101 qualification-making it ideal for cost-sensitive, space-constrained automotive and portable power designs where both efficiency and reliability are critical.

FAQ
Is DMG7408SFG-7 suitable for automotive applications?
Yes. It is fully AEC-Q101 qualified per Rev. 6 datasheet, having passed HTOL, temperature cycling, and unbiased HAST tests. Its –55°C to +150°C operating range, 100% UIS screening, and green RoHS-compliant construction meet requirements for body electronics, infotainment, and exterior lighting systems.
What is the maximum safe operating frequency with DMG7408SFG-7?
Based on its 14.6ns turn-off delay and 10.5nC gate charge, DMG7408SFG-7 supports reliable operation up to 1.5MHz in hard-switched buck converters with appropriate gate drive strength (≥2A peak). At 1MHz, measured switching losses remain below 30% of total losses when RDS(ON) dominates conduction loss.
Does DMG7408SFG-7 require a gate resistor for stability?
A 5–10Ω series gate resistor is recommended to damp ringing caused by Lg–Ciss resonance, especially in high-dV/dt environments. The device's 1.1Ω intrinsic gate resistance and low Crss (61.4pF) minimize Miller effect, but external damping ensures robust EMI performance in noisy automotive or industrial settings.
Can DMG7408SFG-7 replace SO-8 MOSFETs without PCB redesign?
No. While functionally equivalent, PowerDI3333-8 has different pad layout (3.3mm × 3.3mm vs. SO-8's 4.9mm × 6.0mm) and thermal pad geometry. A dedicated footprint is required-however, its 33% smaller board area and superior RθJA make it advantageous for new designs targeting miniaturization and thermal performance.
