Product details
Overview
DMP3008SFGQ-7 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in PowerDI®3333-8 package, featuring 17mΩ RDS(ON) at VGS = −10V, −8.6A continuous drain current at 25°C, and AEC-Q101 qualification for automotive reliability. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters and backlight power stages.
For engineers reviewing the DMP3008SFGQ-7 datasheet, DMP3008SFGQ-7 pinout, DMP3008SFGQ-7 application, or DMP3008SFGQ-7 equivalent, key selection criteria include its low on-resistance at −4.5V gate drive (25mΩ), thermally efficient 33% board-area reduction vs. SO-8, and validated AEC-Q101 stress performance for automotive power management.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) while maintaining fast switching characteristics: 10.5ns turn-on delay, 40ns fall time, and 47nC total gate charge at −10V. Its body diode exhibits −0.7V forward voltage at −1A, enabling efficient reverse conduction in buck converter freewheeling paths.
The device operates across −55°C to +150°C junction temperature range with 7.1°C/W junction-to-case thermal resistance. Thermal design leverages the PowerDI3333-8's exposed drain pad and 1-inch copper plate layout, achieving 57°C/W junction-to-ambient under steady-state conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3415L-7 | Lower RDS(ON) (14mΩ @ −4.5V) but higher Qg (52nC); same PowerDI3333-8 package. | Better conduction loss at light loads; slower switching increases gate drive loss above 200kHz. | Select for <100kHz DC-DC where conduction dominates; avoid in high-frequency LED dimming. |
| SI3457DV-T1-GE3 | Higher RDS(ON) (32mΩ @ −4.5V); smaller TSOP-6 package; no AEC-Q101 qualification. | Reduced board area but limited thermal capacity; unsuitable for automotive or sustained >3A operation. | Select only for cost-sensitive consumer products with ambient <85°C and non-automotive lifecycle requirements. |
Compared with DMG3415L-7 and SI3457DV-T1-GE3, DMP3008SFGQ-7 delivers optimal balance of low gate charge (47nC), AEC-Q101 reliability, and 25mΩ RDS(ON) at −4.5V-making it preferred for automotive and industrial DC-DC converters requiring both efficiency and long-term stability.

FAQ
What is the maximum safe operating voltage for DMP3008SFGQ-7 in continuous DC applications?
The absolute maximum drain-source voltage (VDSS) is −30V. Operation beyond this rating risks avalanche breakdown and permanent damage. For reliable long-term use, design margins should limit steady-state VDS to ≤−24V in automotive 24V systems to accommodate load-dump transients per ISO 7637-2.
Can DMP3008SFGQ-7 be used as a high-side switch with 3.3V logic-level control?
No-its gate threshold voltage (VGS(th)) ranges from −1.1V to −2.1V, requiring ≥−4.5V gate drive for full enhancement. A 3.3V microcontroller output cannot reliably turn it on; a level-shifter or charge-pump circuit is required to generate sufficient negative gate voltage relative to source.
How does the PowerDI3333-8 package improve thermal performance over SO-8?
PowerDI3333-8 reduces thermal resistance by 57°C/W (vs. ~120°C/W for SO-8) through an exposed drain paddle soldered directly to the PCB ground plane. Its 3.3mm × 3.3mm footprint also allows larger copper pours beneath the device, enhancing heat spreading without increasing board area.
Is DMP3008SFGQ-7 suitable for synchronous rectification in a 500kHz buck converter?
Yes-its 47nC total gate charge and 40ns fall time support efficient operation up to 1MHz. However, gate drive strength must deliver ≥±1A peak current to achieve specified switching times; verify driver capability and layout parasitics to avoid shoot-through or excessive ringing at 500kHz.
