Product details
Overview
DMP2040UND from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in a POWERDI®3333-8 package, rated for -20V VDSS, 36 mΩ RDS(ON) @ VGS = -4.5V, and -5.3A continuous drain current at TA = +25°C. It serves as a compact, low-RDS(ON) power switch in space-constrained DC-DC converter and backlighting circuits.
For engineers reviewing the DMP2040UND datasheet, DMP2040UND pinout, DMP2040UND application, or DMP2040UND equivalent, key selection criteria include its dual-channel P-channel topology, low gate threshold (-0.6 to -1.5 V), fast switching (tF = 18.3 ns), low input capacitance (Ciss = 834 pF), and thermal performance on FR-4 with 88 °C/W RθJA under enhanced layout.
Technical Context
This dual P-channel MOSFET integrates two matched enhancement-mode transistors sharing a common source configuration in a thermally efficient 8-pin PowerDI package. Its low VGS(TH) enables direct logic-level drive from 3.3 V or 5 V controllers without level-shifting.
The device features low Ciss/Coss ratio (834/133 pF) and low Qgd/Qg (2.6/9.6 nC), supporting high-frequency synchronous buck operation up to 2 MHz while minimizing switching losses and EMI generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Maximum blocking voltage for low-voltage P-channel load switching |
| RDS(ON) @ VGS = -4.5 V | 36 mΩ max - Enables <100 mW conduction loss at 5.3 A, critical for portable power efficiency |
| ID (TA = +25°C) | -5.3 A - Continuous current rating under standard PCB layout, defining usable output stage capacity |
| VGS(TH) | -0.6 to -1.5 V - Ensures reliable turn-on with 3.3 V GPIO or PWM controller outputs |
| Ciss | 834 pF - Low input capacitance reduces gate drive power and speeds up switching transitions |
| tF | 18.3 ns - Fast fall time supports high-frequency operation and minimizes overlap loss in synchronous rectification |
| RθJA (enhanced layout) | 88 °C/W - Thermal resistance achievable with 2 oz copper and thermal pad, enabling 1.4 W dissipation |
Pinout & Package
Package: POWERDI®3333-8 (Type UXB), surface-mount, thermally enhanced with exposed drain pads for both channels. Dimensions: 3.30 × 3.30 × 0.80 mm (L × W × H), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D1 | Drain of Channel 1 | High-side or low-side switching node; electrically tied to exposed pad 1 for thermal conduction |
| S1 | Source of Channel 1 | Reference node for Channel 1; internally connected to G2 and S2 in common-source dual configuration |
| G1 | Gate of Channel 1 | Control input requiring -4.5 V for full enhancement; low Ciss eases drive requirements |
| D2 | Drain of Channel 2 | Independent switching node; electrically tied to exposed pad 2 for separate thermal path |
| S2 | Source of Channel 2 | Reference node for Channel 2; shared with S1 and G2 per internal connection diagram |
| G2 | Gate of Channel 2 | Independent control input; matched threshold and RDS(ON) to G1 for balanced dual operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual P-channel topology | Enables compact half-bridge or dual-load switching without external level shifters or N-channel gate drivers |
| Low RDS(ON) @ -4.5 V | 36 mΩ ensures ≤1 W total conduction loss across both channels at 3 A each, critical for battery-powered efficiency |
| Low VGS(TH) | -0.6 to -1.5 V allows direct interface with 3.3 V microcontrollers and PMICs, eliminating auxiliary bias circuitry |
| Low Ciss/Coss ratio | 834/133 pF improves Miller immunity and reduces switching energy, supporting >1 MHz DC-DC operation |
| Thermally optimized package | POWERDI3333-8 provides 13.2 °C/W RθJC to exposed drain pads, enabling higher sustained current vs. SO-8 equivalents |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2040UDM-7 | Same POWERDI3333-8 package, but RDS(ON) = 42 mΩ @ -4.5 V; higher VGS(TH) (-0.7 to -2.0 V) | Marginally lower efficiency at high current; less suitable for 3.3 V drive without gate boosting | Select when cost sensitivity outweighs 15% higher conduction loss and tighter VGS margin is acceptable |
| SI3993DV-T1-GE3 | SO-8 package, RDS(ON) = 45 mΩ @ -4.5 V, RθJA = 110 °C/W (no exposed pad) | Larger footprint and inferior thermal performance; requires larger PCB area and heatsinking | Choose only if legacy SO-8 compatibility or existing board layout constraints prohibit POWERDI3333-8 adoption |
Compared with DMC2040UDM-7 and SI3993DV-T1-GE3, DMP2040UND delivers the lowest RDS(ON), tightest VGS(TH) distribution, and best thermal resistance-making it optimal for high-density, high-efficiency portable power stages where board space and thermal headroom are constrained.

FAQ
What is the maximum continuous drain current for each channel at 70°C ambient?
At TA = +70°C, the continuous drain current per channel is -4.2 A when mounted on a standard FR-4 board with minimum pad layout (RθJA = 148 °C/W). With enhanced thermal layout (2 oz copper + thermal pad), it rises to -10.9 A at TC = +70°C, per datasheet Note 7.
Can DMP2040UND be used in a synchronous buck high-side configuration?
Yes-its -20 V VDSS and low RDS(ON) make it suitable as a high-side P-channel switch in non-inverting buck topologies. Gate drive must swing below source potential; for 5 V input, a -5 V gate drive relative to source ensures full enhancement without exceeding ±12 V VGS rating.
Is the body diode suitable for reverse-current freewheeling in DC-DC applications?
Yes-the body diode has VSD = -0.7 to -1.2 V at -2.9 A and tRR = 9.8 ns, enabling efficient synchronous rectification. Its low QRR (2.7 nC) minimizes recovery loss, especially in high-frequency (>1 MHz) buck converters where reverse recovery dominates switching loss.
Does DMP2040UND meet automotive qualification standards?
No-DMP2040UND is not AEC-Q101 qualified. Diodes Incorporated states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; this part is intended for commercial/industrial use. For automotive designs, contact Diodes directly for qualified alternatives like DMP2040UFDQ-7.
