Product details
Overview
DMP2090UFDB from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in a U-DFN2020-6 (Type B) package, rated for -20V VDSS, 90mΩ RD1D2 at VGS = -4.5V, and -3.2A continuous drain current at TA = +25°C. It serves as a compact, low-RON load switch in space-constrained portable power adaptors and battery-powered systems.
For engineers reviewing the DMP2090UFDB datasheet, DMP2090UFDB pinout, DMP2090UFDB application, or DMP2090UFDB equivalent, key selection criteria include its dual-channel P-MOS topology, 0.6mm max height, ESD-protected gate, low input capacitance (634pF), and thermal resistance of 90°C/W under enhanced PCB layout - all critical for high-density DC-DC output stage and USB-C PD load switching designs.
Technical Context
This device integrates two matched P-channel MOSFETs in a single ultra-small 2.0mm × 2.0mm U-DFN2020-6 (Type B) package with exposed thermal pad. Its gate threshold voltage range (-0.3V to -1.0V) enables reliable turn-on from low-voltage logic (e.g., 3.3V/2.5V GPIO) with minimal drive loss.
The internal schematic shows independent S1/G1/D1 and S2/G2/D2 terminals with no shared source or drain - supporting true dual independent switching paths. Body diode forward voltage is -0.7V to -1.2V at -1.0A, enabling bidirectional reverse-current blocking in back-to-back configurations for USB OTG and battery isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum drain-source blocking voltage for 3.3V/5V rail protection and battery-side switching |
| RD1D2 @ VGS = -4.5V | 37–90mΩ - Low conduction loss enabling ≤100mW dissipation at 3.2A, suitable for thermally constrained PCBs |
| ID (TA = +25°C) | -3.2A - Continuous current rating with 1.39W power dissipation on 1-inch copper pad |
| Ciss | 634pF - Enables fast switching (tD(ON) = 4.2ns) with minimal gate drive energy |
| Qg | 6.8nC - Low total gate charge reduces driver IC loading and improves efficiency in high-frequency PWM control |
| RθJA (enhanced layout) | 90°C/W - Thermal performance validated on FR-4 with 1-inch copper plate, enabling >1.2W safe operation at 70°C ambient |
| VGS(TH) | -0.3 to -1.0V - Ensures full enhancement with standard 3.3V logic outputs without level-shifting |

IC Role / Device Role / Timing Role: Dual P-MOSFET replacing discrete Schottky diodes to reduce conduction loss and improve light-load efficiency. Use Value: 634pF Ciss and 6.8nC Qg support >500kHz switching without excessive gate drive loss; 1.39W PD rating sustains 2A output continuously. |
Use Scenario: Low-power subsystem enable/disable in battery-operated IIoT nodes with multiple sensor rails (e.g., analog front-end, RF transceiver, MCU core). IC Role / Device Role / Timing Role: Independent channel control for rail sequencing and fault-isolation between isolated sensor domains. Use Value: -1.0V VGS(TH) max ensures full turn-on from 1.8V I/O, enabling direct microcontroller GPIO drive without external level shifters. |
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 |
|---|---|---|---|
| DMC2058UVT-7 | Single-channel P-MOS, same U-DFN2020-6 package, 50mΩ @ -4.5V, but lacks dual topology | Requires two devices for dual-path function; increases board area and routing complexity | Select only if independent channel control is unnecessary and cost-per-channel is prioritized |
| Si2301DDS-T1-GE3 | Single P-MOS in SOT-23, 115mΩ @ -4.5V, higher RON, no ESD rating specified | Larger footprint (2.9mm × 1.6mm), no thermal pad, unsuitable for >2A continuous loads | Acceptable only for low-current (<1.5A), non-ESD-sensitive legacy designs with SOT-23 constraints |
Compared with DMC2058UVT-7 and Si2301DDS-T1-GE3, the DMP2090UFDB uniquely delivers dual independent P-MOS channels in a 2.0mm × 2.0mm footprint with guaranteed ESD protection, sub-100mΩ RON, and thermal performance validated for 1.39W dissipation - making it the only option that satisfies simultaneous size, efficiency, and reliability requirements in next-gen portable power systems.

FAQ
What is the maximum junction temperature and thermal derating behavior of DMP2090UFDB?
The device is rated for TJ = -55°C to +150°C. At 150°C, RD1D2 increases by ~20% versus 25°C (per Figure 6). Derating begins at TA > 70°C for the 1.39W power rating; above this, allowable current drops linearly to zero at 150°C ambient using the 90°C/W RθJA value.
Can DMP2090UFDB be used in back-to-back configuration for AC-coupled signal switching?
No - it is not designed for AC signal switching. Its body diode is optimized for DC blocking in power paths, and the gate oxide is not rated for bidirectional VGS stress. The datasheet specifies only unidirectional VGS operation (±8V), and no AC small-signal parameters (e.g., gm, fT) are provided.
Is the U-DFN2020-6 (Type B) package compatible with standard reflow profiles for lead-free soldering?
Yes - the package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports peak reflow temperatures up to 260°C. The NiPdAu terminal finish ensures reliable wetting with SAC305 and other lead-free pastes; recommended soak time is 60–120 seconds at 150–200°C before ramp-up.
Does DMP2090UFDB support avalanche energy rating, and what is its practical use case?
Yes - it has a rated avalanche energy EAS of 7mJ (L = 0.1mH, IAS = -11A). This rating applies to single-pulse inductive turn-off events, such as relay coil de-energization or motor phase commutation. It is not intended for repetitive avalanche operation and must be verified per application using the SOA curve (Figure 12).
