Product details
Overview
DMT4011LFG-13 from Diodes Incorporated is a 40V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 11.5mΩ RDS(ON) at VGS = 10V and 30A continuous drain current at TC = +25°C. It features low gate charge (Qg = 15.1nC), 100% production-tested UIS robustness, and optimized FOM (Qgd × RDS(ON)) for high-frequency DC-DC converter switching stages.
For engineers reviewing the DMT4011LFG-13 datasheet, DMT4011LFG-13 pinout, DMT4011LFG-13 application, or DMT4011LFG-13 equivalent, key selection criteria include RDS(ON) at 4.5V (17.8mΩ), thermal resistance RθJC = 8°C/W, avalanche energy EAS = 21.4mJ, and body diode reverse recovery charge QRR = 5.1nC in compact thermally efficient packaging.
Technical Context
This MOSFET employs trench-gate silicon technology to achieve low conduction loss while maintaining fast switching performance. Its 8°C/W junction-to-case thermal resistance enables high-power density operation when mounted on PCB copper pads, and its 100% UIS-tested construction ensures reliability under inductive load transients.
The device supports dual-gate-voltage drive (4.5V and 10V), with gate threshold voltage VGS(TH) tightly specified between 1V and 3V. Dynamic parameters-including Ciss = 767pF, Coss = 238pF, and Qgd = 3.2nC-support stable operation in synchronous buck converters operating up to 1MHz.

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 |
|---|---|---|---|
| DMT6004LPS-13 | 60V VDSS, 4.5mΩ @ 10V, PowerDI5060 package (larger footprint, lower RθJA) | Better voltage margin but higher gate charge (22nC) and larger board area | Select when system requires >40V transient tolerance and can accommodate 5.0mm × 6.0mm layout |
| SiR872DP-T1-GE3 | 40V VDSS, 10.5mΩ @ 10V, PowerPAK SO-8L package, Qg = 16.5nC | Similar RDS(ON) but higher RθJC (12°C/W) and no production UIS test data published | Prefer when existing SO-8L footprint reuse is required and avalanche stress is not expected |
Compared with DMT6004LPS-13 and SiR872DP-T1-GE3, DMT4011LFG-13 delivers superior thermal efficiency (RθJC = 8°C/W), verified UIS robustness, and smaller 3.3mm × 3.3mm footprint-making it optimal for space- and thermally constrained high-reliability DC-DC designs.

FAQ
What is the maximum safe operating temperature for DMT4011LFG-13?
The device has a rated junction temperature range of –55°C to +150°C. Under continuous operation, maximum case temperature must be limited to +70°C to sustain 24A ID, per datasheet derating curves. Thermal design must ensure RθJA remains ≤62°C/W on FR-4 with 1-inch² 2oz copper pad to avoid exceeding TJ(max).
Can DMT4011LFG-13 be driven directly by a 3.3V GPIO?
No-its gate threshold voltage VGS(TH) ranges from 1V to 3V, but RDS(ON) is only guaranteed at VGS ≥ 4.5V (17.8mΩ). At 3.3V, conduction loss increases significantly and is not characterized. A level-shifted or buffered 4.5V+ gate drive is required for reliable low-RDS(ON) operation.
Does DMT4011LFG-13 have integrated ESD protection?
The datasheet does not specify human-body model (HBM) or charged-device model (CDM) ESD ratings. While the PowerDI3333-8 package provides mechanical robustness, external TVS or RC filtering is recommended on gate and drain lines in environments with electrostatic discharge risk.
Is DMT4011LFG-13 qualified for automotive use?
Per the datasheet, this part is not AEC-Q101 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-none of which apply to DMT4011LFG-13. It is intended for industrial and commercial applications only.
