Product details
Overview
DMP3035LSS from Diodes Incorporated is a single P-channel enhancement-mode MOSFET designed for high-efficiency power management, featuring -30V VDSS, 14mΩ RDS(ON) @ VGS = -20V, and -10A continuous drain current at TA = +25°C. It operates in DC-DC converters and backlighting circuits where low conduction loss and fast switching are critical.
For engineers reviewing the DMP3035LSS datasheet, DMP3035LSS pinout, DMP3035LSS application, or DMP3035LSS equivalent, key selection criteria include gate threshold voltage (-1V to -2V), input capacitance (1655pF), thermal resistance (60°C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET uses planar trench-gate technology to achieve low RDS(ON) while maintaining robust switching performance. Its -2V typical VGS(TH) enables direct drive from 3.3V/5V logic with margin, and its 240pF Crss supports clean turn-off in synchronous buck topologies.
The device exhibits 87°C/W junction-to-ambient thermal resistance on FR-4 board, with normalized RDS(ON) rising only ~1.4× from -55°C to +150°C. Its 30.7nC total gate charge at VGS = -10V balances drive strength and switching loss in medium-frequency (<500kHz) power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Withstands reverse-biased drain-source voltage up to 30V in high-side switch or load-switch configurations |
| RDS(ON) | 14mΩ @ VGS = -20V - Enables ≤1.4W conduction loss at 10A, suitable for compact 2W power stages |
| ID (continuous) | -10A @ TA = +25°C - Supports sustained 8.8A output in thermally constrained 70°C ambient environments |
| Ciss | 1655pF @ VDS = -20V - Determines gate drive energy requirement and impacts EMI filtering design |
| tF | 30ns - Enables fast turn-off to minimize shoot-through risk in half-bridge drivers |
| RθJA | 60°C/W - Requires minimal copper area (1 in² FR-4, 2 oz Cu) to maintain TJ < 150°C at full load |
| VGS(TH) | -1V to -2V - Ensures reliable turn-on with standard logic-level gate drivers without level-shifting |
Pinout & Package
Package: SO-8 surface-mount package with matte tin–annealed copper leadframe, UL 94V-0 molded plastic body, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source | Common source connection for internal parallel die; tied to PCB ground plane for thermal and electrical return |
| 5, 6, 7, 8 | Drain | High-current drain terminals connected internally to power rail; require wide copper pours for heat dissipation |
| Gate (Pin 3 of internal schematic) | Control input | Single gate terminal (shared across all pins per SO-8 layout); requires <2.3Ω series resistance to damp ringing |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at low VGS | 18mΩ @ VGS = -10V enables efficient operation with 3.3V microcontroller GPIOs |
| Fast switching speed | 8ns rise time and 30ns fall time reduce transition losses in 300–500kHz DC-DC converters |
| AEC-Q101 qualified | Validated for automotive temperature cycling (-40°C to +125°C) and humidity testing per stress test standards |
| Green packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets automotive RoHS compliance requirements |
| Low gate leakage | ±100nA IGSS at ±20V ensures stable gate bias in battery-powered always-on circuits |
Applications

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 | RDS(ON) = 20mΩ @ VGS = -4.5V; Ciss = 1200pF; SO-8 package | Higher RDS(ON) increases conduction loss by ~43% at 6.2A; lower Ciss reduces gate drive demand | Select when gate drive capability is limited but thermal budget allows higher I²R loss |
| SI2305DS | RDS(ON) = 48mΩ @ VGS = -4.5V; SOT-23 package; 4.2A ID rating | Lower current rating and higher on-resistance restrict use to sub-5A loads; smaller footprint saves board space | Choose for space-constrained consumer electronics where peak current ≤4A and thermal mass is adequate |
Compared with DMP3035LSS, DMG3415L trades higher conduction loss for reduced gate charge, while SI2305DS sacrifices current handling and efficiency for miniaturization-neither matches the 10A/14mΩ balance at -20V drive in SO-8.

FAQ
Is DMP3035LSS suitable for hot-swap applications?
Yes. Its -30V VDSS, low RDS(ON), and 80A pulsed drain rating support controlled inrush current limiting. The 1µA max IDSS ensures minimal leakage during standby, and the SO-8 package provides sufficient thermal mass for brief overload events without derating.
What is the maximum operating frequency for DMP3035LSS in a synchronous buck converter?
Based on its 30ns fall time, 8ns rise time, and 30.7nC Qg, DMP3035LSS is optimized for 300–500kHz operation. At 1MHz, switching losses increase significantly due to gate charge and output capacitance limitations, requiring careful gate driver sizing and layout optimization.
Does DMP3035LSS require a gate resistor for stability?
Yes. A 2.2Ω to 10Ω series gate resistor is recommended to dampen ringing caused by its 2.3Ω intrinsic gate resistance and 1655pF Ciss. This prevents false turn-on from dv/dt coupling and ensures clean transitions in high-noise industrial environments.
How does the -55°C to +150°C operating range impact design margins?
The device maintains functional VGS(TH) and RDS(ON) across this range, with RDS(ON) increasing only ~1.4× at 150°C. Designers must size PCB copper and heatsinking to keep TJ ≤150°C under worst-case ambient and power dissipation, using the 60°C/W RθJA value.
