Product details
Overview
DMTH3004LFG-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for 30V VDSS, 5.5mΩ RDS(ON) @ 10V VGS, and 75A continuous drain current at TC = +25°C. It delivers low conduction loss and high pulsed current capability (250A), optimized for automotive body control electronics and DC-DC converter primary-side switching.
For engineers reviewing the DMTH3004LFG-7 datasheet, DMTH3004LFG-7 pinout, DMTH3004LFG-7 application, or DMTH3004LFG-7 equivalent, key selection criteria include its 4.1mΩ typical RDS(ON), 100% UIS-rated avalanche ruggedness, thermally efficient PowerDI3333-8 footprint, and AEC-Q101-compliant variant availability (DMTH3004LFGQ).
Technical Context
This MOSFET employs a trench-gate silicon process to achieve ultra-low RDS(ON) while maintaining fast switching performance-evidenced by 8nC Qgd and 44nC total gate charge at 10V. Its 3°C/W RθJC enables high-power dissipation (50W) when mounted on a heatsink.
The device integrates a robust body diode with 25ns reverse recovery time and 37nC QRR, supporting synchronous rectification and freewheeling in hard-switched topologies. Thermal stability is confirmed across –55°C to +175°C junction range, with normalized RDS(ON) variation ≤2.0× over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage before avalanche onset; suitable for 24V automotive and industrial bus systems. |
| RDS(ON) @ 10V | 4.1mΩ (typ), 5.5mΩ (max) - Enables <0.8W conduction loss at 20A, critical for high-efficiency power stages. |
| ID (TC=25°C) | 75A - Continuous current rating under heatsink-cooled conditions; defines safe operating area for sustained load handling. |
| Qg @ 10V | 44nC - Gate drive energy requirement; determines driver strength needed for <25ns turn-on delay and 4.3ns rise time. |
| EAS | 110mJ - Single-pulse avalanche energy rating; ensures reliability during inductive switching transients without derating. |
| RθJC | 3°C/W - Junction-to-case thermal resistance; allows direct thermal interface to heatsinks for high-power density designs. |
| tRR | 25ns - Body diode reverse recovery time; minimizes switching loss and voltage overshoot in freewheeling paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH3004LFGQ | AEC-Q101 qualified; identical electrical specs but validated for automotive temperature cycling and humidity testing. | Required for engine bay, transmission control, or ADAS modules where qualification traceability is mandatory. | Select when automotive PPAP documentation, lot-level test reports, and extended temperature validation are contractually required. |
| IPB017N10N5 | 100V VDSS, 1.7mΩ RDS(ON) @ 10V, larger TO-263-7 package; higher voltage margin but 2.5× larger footprint. | Suitable for 48V mild-hybrid systems or industrial UPS where 30V rating is insufficient. | Choose only if system bus voltage exceeds 30V or if higher avalanche margin justifies increased board area and cost. |
Compared with DMTH3004LFG-7, DMTH3004LFGQ adds automotive qualification without altering electrical behavior, while IPB017N10N5 trades voltage headroom and size for lower RDS(ON)-making DMTH3004LFG-7 optimal for cost- and space-sensitive 24V automotive and industrial switching where 30V rating is sufficient.

FAQ
What is the maximum junction temperature and thermal resistance of DMTH3004LFG-7?
The absolute maximum junction temperature is +175°C. Its thermal resistance from junction to case (RθJC) is guaranteed at 3°C/W, measured from the die to the exposed drain pad. This value assumes proper soldering to a copper thermal pad per Diodes' recommended layout; RθJA is user-dependent and rated at 60°C/W on standard FR-4 with 1-inch² copper.
Is DMTH3004LFG-7 suitable for synchronous rectification in DC-DC converters?
Yes. With 0.7V typical VSD at 1A and 25ns body diode tRR, it supports efficient synchronous rectification in buck and flyback topologies up to 500kHz. Its low Qgd/RDS(ON) ratio minimizes shoot-through risk and improves light-load efficiency versus Schottky alternatives.
Does DMTH3004LFG-7 require gate resistors for reliable operation?
A gate resistor (typically 3–10Ω) is recommended to dampen ringing and control dV/dt during switching. The datasheet specifies tD(ON) = 6.2ns and tF = 8ns with Rg = 3Ω; omitting it risks oscillation due to low gate resistance (0.6Ω) and high Ciss (2370pF), especially in high-noise automotive environments.
How does the PowerDI3333-8 package compare to SO-8 in thermal performance?
PowerDI3333-8 provides 3× lower RθJC (3°C/W vs ~10°C/W for SO-8) due to direct die-to-pad thermal path and four paralleled drain terminals. Its 33% smaller footprint also reduces parasitic inductance, improving EMI and transient response-critical in high-frequency power stages.
