Product details
Overview
DMP2066UFDE-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in U-DFN2020-6 Type E package, rated for -20V VDS, 36mΩ RDS(on) at VGS = -4.5V, and -6.2A continuous drain current at TA = +25°C. It serves as a low-profile power switch in compact DC-DC converters and load-switching circuits.
For engineers reviewing the DMP2066UFDE-7 datasheet, DMP2066UFDE-7 pinout, DMP2066UFDE-7 application, or DMP2066UFDE-7 equivalent, key selection criteria include gate threshold voltage (-0.4 to -1.1V), low RDS(on) at 2.5V drive, thermal resistance (61°C/W steady-state), and JEDEC-qualified reliability for industrial power management designs.
Technical Context
This MOSFET employs trench-gate silicon process technology to achieve low on-resistance while maintaining fast switching performance. Its -1.8V gate threshold enables direct interface with 1.8V/2.5V logic controllers without level shifting.
The device integrates a body diode with VSD = -0.7 to -1.2V at IS = -2.1A and exhibits Ciss = 1537pF, Coss = 146pF, and Qg = 14.4nC - parameters optimized for high-frequency synchronous buck topologies and reverse-polarity protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -20V maximum drain-source blocking voltage - supports 12V rail protection and USB PD input stages |
| RDS(on) | 36mΩ @ VGS = -4.5V - enables <100mW conduction loss at 5A load |
| ID (continuous) | -6.2A @ TA = +25°C - suitable for 5V/3A load switches with minimal heatsinking |
| VGS(th) | -0.4 to -1.1V - ensures turn-on with standard 1.8V/2.5V GPIOs |
| Qg | 14.4nC - balances switching speed and gate driver stress in 500kHz–1MHz SMPS |
| RθJA | 61°C/W (with recommended pad layout) - allows 0.66W dissipation at ≤85°C ambient |
| Ciss | 1537pF - defines Miller capacitance impact on gate drive loop stability |
Pinout & Package
U-DFN2020-6 Type E is a 2.0mm × 2.0mm × 0.6mm leadless surface-mount package with exposed thermal pad on bottom side and six terminals arranged in dual-row configuration. Pin 1 is marked by a dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 6 | Drain (D) | Internally connected drain terminals - share current path and thermal mass for low-inductance high-current routing |
| 3, 4 | Source (S) | Common source connection - ties to ground plane for optimal return path and thermal conduction |
| 5 | Gate (G) | Control input - requires <15nC charge for full enhancement; sensitive to ESD (±12V rating) |
Key Features
| Feature | Design Value |
|---|---|
| 0.6mm profile | Enables use in ultra-thin portable electronics where Z-height is constrained to <1.0mm |
| 4mm² PCB footprint | Reduces board area by >50% vs. SO-8 or TSOP-6 equivalents without sacrificing current handling |
| Low RDS(on) at 2.5V | 56mΩ operation at VGS = -2.5V - supports battery-powered systems with weak gate drive capability |
| JEDEC-qualified reliability | Qualified per AEC-Q200 stress test standards - validated for extended temperature cycling and moisture resistance |
| Halogen- and antimony-free | <900ppm Br, <900ppm Cl, <1000ppm Sb - meets IPC-1752a Class 3 environmental compliance for green manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2302UK-7 | RDS(on) = 48mΩ @ -4.5V; larger U-DFN2020-6 but non-Type E footprint; no JEDEC qualification | Lacks AEC-Q200 validation; higher RDS(on) increases conduction loss in 5A+ loads | Prefer for cost-sensitive consumer designs where qualification and thermal margin are secondary |
| AO3401A | RDS(on) = 44mΩ @ -4.5V; SOT-23 package; RθJA = 200°C/W - limits max ID to ~2.2A | Lower current capacity and inferior thermal performance restrict use to <2A loads | Select only when board space permits SOT-23 and peak load remains below 2A |
Compared with DMG2302UK-7 and AO3401A, DMP2066UFDE-7 delivers superior thermal performance (61°C/W), tighter gate threshold distribution (-0.4 to -1.1V), and JEDEC-qualified reliability - making it the preferred choice for thermally constrained, high-reliability industrial and portable power gating.

FAQ
What is the maximum safe operating junction temperature for DMP2066UFDE-7?
The device is rated for TJ from -55°C to +150°C. Maximum continuous operation occurs at TJ ≤ 150°C, which corresponds to TA ≤ 85°C when mounted on FR-4 with 1-inch² copper pad (PD = 2.03W). Derating is required above 85°C ambient per the RθJA = 61°C/W curve.
Can DMP2066UFDE-7 be used in a synchronous rectifier configuration?
No - DMP2066UFDE-7 is a single P-channel MOSFET without integrated gate driver or bootstrap circuitry. While its low RDS(on) and fast switching (tf = 35.5ns) support high-efficiency freewheeling, synchronous rectification requires complementary N-channel control or dedicated controller ICs not provided by this device.
Is the U-DFN2020-6 Type E package compatible with standard reflow profiles?
Yes - the package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260°C, 60s max above 217°C). The 0.6mm profile and thermal pad require controlled solder paste volume (0.12mm stencil) to prevent tombstoning and ensure void-free thermal interface.
Does DMP2066UFDE-7 have avalanche energy rating specified?
No - the datasheet does not specify single-pulse avalanche energy (EAS) or repetitive avalanche ratings. Designers must avoid operation in avalanche breakdown region and implement external clamping (e.g., TVS diodes) if inductive load switching introduces voltage overshoot exceeding -20V VDS.
