Product details
Overview
DMP3035SFG from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in PowerDI3333-8 package, rated for -9.5A continuous drain current at VGS = -10V, with RDS(ON) of 20mΩ max, designed for high-efficiency DC-DC converters and backlighting power switches in space-constrained industrial and consumer systems.
For engineers reviewing the DMP3035SFG datasheet, DMP3035SFG pinout, DMP3035SFG application, or DMP3035SFG equivalent, this part supports low-voltage P-channel switching with thermally optimized thermal resistance (RθJA = 55°C/W with 1-inch2 copper), AEC-Q101 qualification, and halogen/antimony-free "Green" construction - critical for automotive-grade power management design reviews.
Technical Context
This MOSFET operates as a high-side load switch or synchronous rectifier in buck converters, leveraging its -1.7V typical gate threshold voltage and low 214pF reverse transfer capacitance (Crss) to minimize switching losses and improve control loop stability. Its 35.5nC total gate charge at VGS = -10V enables predictable turn-on timing under 10ns delay.
The device uses a single-die PowerDI3333-8 package with four parallel drain terminals and dual source terminals, delivering 6.14°C/W junction-to-case thermal resistance and supporting pulsed drain currents up to -70A with 1% duty cycle - essential for transient-heavy power delivery stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Maximum blocking voltage for 12V/24V rail protection and buck converter high-side operation |
| RDS(ON) max | 20mΩ @ VGS = -10V - Enables ≤1.6W conduction loss at 9.5A, reducing thermal derating in compact PCB layouts |
| ID continuous | -9.5A @ TA = +25°C - Sustains full-rated load in ambient-cooled applications without forced airflow |
| Qg | 35.5nC @ VGS = -10V - Determines gate driver current requirement (~3.6mA avg for 1MHz switching) |
| RθJC | 6.14°C/W - Allows direct heatsinking via PCB copper pour to maintain TJ < 150°C under 2.3W steady-state dissipation |
| VGS(TH) | -1.0 to -2.5V - Ensures reliable turn-on with standard logic-level gate drivers (e.g., -5V or -10V supplies) |
| Ciss | 1633pF - Sets input impedance for gate drive network design and EMI filtering requirements |
Pinout & Package
Package: PowerDI3333-8 - surface-mount, thermally enhanced 8-pin molded plastic package with four parallel drain leads (pins 4–7), two source leads (pins 1–2), and dual gate connections (pins 3 and 8) for low-inductance layout and improved current sharing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Source | Parallel-connected source terminals reduce on-resistance contribution and improve thermal spreading across PCB copper |
| 3, 8 | Gate | Dual gate inputs lower effective gate loop inductance and suppress ringing during fast switching transitions |
| 4–7 | Drain | Four paralleled drain terminals support high-current paths while minimizing trace resistance and localized heating |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) | 15mΩ typical at VGS = -10V - cuts conduction loss by >30% vs. legacy SO-8 P-MOSFETs in same footprint |
| Thermally optimized package | RθJA = 55°C/W with 1-inch2 copper - enables 2.3W continuous power dissipation without external heatsink |
| AEC-Q101 qualified | Stress-tested per automotive reliability standards - suitable for under-hood and infotainment power modules |
| Halogen/antimony-free "Green" construction | <900ppm Br, <900ppm Cl, <1000ppm Sb - meets EU RoHS 3 and JIG-STD-020 moisture sensitivity Level 1 |
| Small board area | 33% of SO-8 footprint - allows denser power stage integration in portable and LED driver PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3415L-7 | RDS(ON) = 28mΩ @ VGS = -4.5V; SO-8 package; RθJA = 62°C/W | Larger footprint; higher thermal resistance limits continuous current to -6.5A at +70°C ambient | Preferred where SO-8 compatibility is required and board space permits larger thermal pad |
| DMP3025SFG-7 | RDS(ON) = 15mΩ @ VGS = -10V; identical PowerDI3333-8 package; 2.5V lower |VDSS| (-25V) | Not suitable for 30V bus applications; limited to 12V/19V systems with tighter voltage margins | Select when lower on-resistance is prioritized and system max VDS remains ≤25V |
Compared with DMG3415L-7, DMP3035SFG delivers 29% lower RDS(ON) and 13% better thermal performance in 33% less board area; versus DMP3025SFG, it trades 5V breakdown margin for identical package size and superior 30V system robustness.

FAQ
Is DMP3035SFG suitable for automotive applications?
Yes - DMP3035SFG is qualified to AEC-Q101 standards and operates from -55°C to +150°C, making it appropriate for non-safety-critical automotive functions including LED lighting, body control modules, and infotainment power rails. It is not authorized for life-support systems without explicit Diodes Incorporated approval.
What is the maximum safe operating frequency for DMP3035SFG in a buck converter?
Based on its 35.5nC gate charge and 25.8ns fall time, DMP3035SFG supports switching frequencies up to 2 MHz in well-designed gate-drive circuits with <3Ω source/sink impedance. Efficiency peaks between 300 kHz and 1 MHz due to optimal balance of conduction and switching losses.
Can DMP3035SFG replace an N-channel MOSFET in high-side configurations?
No - DMP3035SFG is a P-channel device intended for high-side switching without level-shifting circuitry. Replacing an N-channel high-side switch would require redesigning gate drive to accommodate negative VGS; it cannot be directly substituted without verifying biasing, timing, and voltage margin compatibility.
Does DMP3035SFG include integrated ESD protection?
No - DMP3035SFG does not integrate ESD protection circuitry. Its gate oxide is rated for ±25V VGS, but external TVS diodes or series gate resistors are recommended in environments with >2kV HBM risk to prevent gate oxide rupture during handling or system transients.
