Product details
Overview
DMP2900UW-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT323 package, rated for -20V VDSS, 750mΩ RDS(ON) at VGS = -4.5V, and -0.6A continuous drain current at +25°C. It serves as a low-voltage load switch or synchronous rectifier in compact DC-DC converters.
For engineers reviewing the DMP2900UW-7 datasheet, DMP2900UW-7 pinout, DMP2900UW-7 application, or DMP2900UW-7 equivalent, key selection criteria include gate threshold voltage (-0.5V to -1.0V), low input capacitance (49pF Ciss), fast switching (tF = 89ns), ESD-protected gate, and thermal resistance (272°C/W with copper pad).
Technical Context
This MOSFET operates in enhancement mode with negative gate control logic, requiring VGS ≤ -0.5V to initiate conduction. Its low RDS(ON) at low |VGS| (1.5Ω @ -1.8V) enables efficient operation in 1.8V–3.3V logic-controlled power rails.
The device integrates an intrinsic body diode with VSD = -1.2V at -150mA and exhibits low dynamic parameters: Qg = 0.7nC, Qgd = 0.1nC, and tD(OFF) = 213ns - supporting high-frequency switching up to ~1MHz in buck converter topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - maximum blocking voltage in off-state; suitable for 12V rail and lower systems |
| RDS(ON) | 750mΩ @ VGS = -4.5V - enables <150mW conduction loss at 430mA load |
| VGS(TH) | -0.5V to -1.0V - ensures turn-on with standard 1.8V/2.5V/3.3V I/O drivers |
| Ciss | 49pF - reduces gate drive power and improves switching efficiency at 500kHz–1MHz |
| PD | 0.5W (with 1-inch² copper) - supports 0.6A continuous operation in thermally enhanced PCB layout |
| tF | 89ns - limits switching transition losses in high-duty-cycle load switch applications |
Pinout & Package
SOT323 package: ultra-small surface-mount outline (2.15 × 2.10 × 0.95 mm), 3-terminal plastic-molded case with matte tin annealed terminals; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for P-channel conduction | Connected to higher potential rail; referenced for gate control logic |
| 2 (Gate) | Control electrode for channel formation | ESD-protected; requires <1.0V negative swing below source to fully enhance |
| 3 (Drain) | Load-side current terminal | Connected to output node; hosts body diode cathode for reverse-current blocking |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | VGS(TH) down to -0.5V enables direct interface with 1.8V GPIO without level shifting |
| Low input capacitance | Ciss = 49pF minimizes gate drive energy and propagation delay in high-speed switching |
| ESD-protected gate | HBM rating ≥2kV - eliminates need for external gate protection in board-level ESD environments |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets automotive and industrial green standards |
Applications
| Battery-Powered Load Switch | USB Port Power Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2302UK-7 | RDS(ON) = 65mΩ @ VGS = -4.5V; SOT-23 package; higher ID (−2.0A) | Higher current handling but larger footprint and higher gate charge (Qg = 3.5nC) | Select when >0.6A load current or lower RDS(ON) is required; verify PCB space and drive strength. |
| AO3401 | RDS(ON) = 85mΩ @ VGS = -4.5V; SOT-23; higher PD (1.4W) | Higher thermal capability but no specified ESD rating; not "Green" compliant | Prefer where cost sensitivity outweighs environmental compliance or ESD robustness requirements. |
Compared with DMG2302UK-7 and AO3401, DMP2900UW-7 offers optimal trade-off of ultra-low gate drive demand, industry-leading green credentials, and sufficient RDS(ON) for sub-0.6A space-constrained loads - making it ideal for wearables, IoT edge nodes, and compact industrial sensors.

FAQ
What is the maximum continuous drain current for DMP2900UW-7 at +70°C ambient?
The maximum continuous drain current is -0.5A at TA = +70°C with the recommended 1-inch² copper pad layout. This derating reflects thermal limitations of the SOT323 package under sustained power dissipation; operation above this current requires active cooling or pulse-width-limited duty cycles.
Does DMP2900UW-7 have a built-in body diode, and what is its forward voltage?
Yes, it includes an integrated body diode with typical forward voltage VSD = -1.2V at -150mA and VGS = 0V. This diode conducts from source to drain and is characterized for reverse recovery time (tRR = 10.5ns) and charge (QRR = 1.8nC), supporting synchronous rectification in buck topologies.
Can DMP2900UW-7 be used with 1.8V logic-level gate drive?
Yes - its gate threshold voltage range (-0.5V to -1.0V) ensures reliable turn-on with 1.8V logic referenced to source. At VGS = -1.8V, RDS(ON) is 1.5Ω, supporting up to -450mA with acceptable conduction loss; full enhancement occurs at -4.5V for lowest RDS(ON).
Is DMP2900UW-7 qualified for automotive applications?
No - DMP2900UW-7 is not AEC-Q101 qualified. While it meets industrial temperature range (-55°C to +150°C) and RoHS/green specifications, Diodes explicitly states that automotive-grade versions require separate qualification (PPAP, IATF 16949 manufacturing, AEC-Q101 stress testing), and this part number is not listed in their automotive product matrix.
