Product details
Overview
DMP2039UFDE from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for high-efficiency load switching in space-constrained power management systems. It delivers 27 mΩ RDS(ON) at VGS = −4.5 V, −6.7 A continuous drain current, and operates with −25 V VDSS in a U-DFN2020-6 (Type E) package - enabling compact battery protection circuits in portable electronics.
For engineers reviewing the DMP2039UFDE datasheet, DMP2039UFDE pinout, DMP2039UFDE application, or DMP2039UFDE equivalent, key selection criteria include its low-profile 0.6 mm height, ESD-protected gate, 4 mm² PCB footprint, and verified performance under −1.8 V gate drive for ultra-low-voltage battery management.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) while preserving fast switching characteristics: total gate charge is 28.2 nC at VGS = −4.5 V, with tD(OFF) = 137.6 ns and Qgd/Qgs ratio of ~1.56 - supporting efficient synchronous rectification and PWM-controlled load switching.
Its thermal design targets high-power-density layouts: RθJA is 63 °C/W on 2 oz copper with thermal bias, and junction-to-case resistance is 10.8 °C/W - enabling stable operation up to +150 °C junction temperature with controlled pulse-width duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −25 V - supports input rails up to 24 V nominal battery systems without breakdown risk |
| RDS(ON) @ VGS = −4.5 V | 27 mΩ max - limits conduction loss to ≤0.12 W at 2 A load current |
| ID Continuous @ TA = +25°C | −6.7 A - enables single-device load switching for USB-C PD sink paths and PMIC output stages |
| Qg @ VGS = −4.5 V | 28.2 nC - determines gate driver strength requirement for <100 ns turn-on in 500 kHz SMPS |
| RθJA (2 oz Cu, thermal pad) | 63 °C/W - allows 2.0 W steady-state dissipation with ≤126 °C rise above 25 °C ambient |
| Package | U-DFN2020-6 (Type E) - 2.0 × 2.0 mm body, 0.6 mm profile, bottom-exposed thermal pad |
| VGS(TH) | −0.4 to −1.0 V - ensures reliable turn-on with 1.8 V logic-level controllers and low-VCC microcontrollers |
Pinout & Package
U-DFN2020-6 (Type E) is a 2.0 mm × 2.0 mm, 0.6 mm height, thermally enhanced leadless package with exposed drain pad on bottom surface. Pin 1 is marked by chamfered corner; terminals are NiPdAu-plated for solderability per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Common source connection; pins tied internally to substrate; requires low-impedance ground plane routing |
| 4 | Gate | Control terminal; ESD-protected; driven by logic-level signal; minimal capacitance (Ciss = 2530 pF) |
| 5, 6 | Drain | Power output node; connected to exposed bottom thermal pad; must be soldered to large copper area for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 1.8 V gate drive | 40 mΩ max - enables direct interface with 1.8 V I/O domains without level-shifting circuitry |
| ESD-protected gate | HBM >2 kV - eliminates need for external gate protection diodes in handheld device designs |
| 0.6 mm profile | Height constraint met for stacked PCBs and ultra-thin wearables - no mechanical interference with adjacent components |
| 4 mm² PCB footprint | Reduces board area by >50% vs. SO-8 equivalents - critical for multi-rail PMIC subsystems in smartphones |
| Halogen- and antimony-free "Green" construction | <900 ppm Br/Cl, <1000 ppm Sb - satisfies IPC-1752a Class 3 reporting and EU SCIP database requirements |

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 |
|---|---|---|---|
| DMG2307L-7 | RDS(ON) = 30 mΩ @ −4.5 V; larger SOT-23-6 package (2.9 × 2.8 mm); higher RθJA = 190 °C/W | Suitable for prototyping on through-hole or mixed-technology boards where U-DFN reflow is unavailable | Select when manual assembly or legacy PCB tooling prohibits U-DFN2020-6 use |
| AO3401 | RDS(ON) = 44 mΩ @ −4.5 V; same U-DFN2020-6 footprint but non-ESD-gated; RoHS-compliant only (not "Green") | Acceptable for cost-sensitive consumer products where ESD robustness is managed at system level | Select only if gate ESD protection is implemented externally and halogen-free compliance is not required |
Compared with DMG2307L-7 and AO3401, DMP2039UFDE provides superior thermal performance (63 °C/W vs. ≥190 °C/W), lower conduction loss (27 mΩ vs. ≥30 mΩ), and integrated ESD protection - making it optimal for production-grade, miniaturized battery-powered systems requiring long-term reliability.

FAQ
What is the maximum continuous drain current at 70°C ambient?
At TA = +70°C with recommended FR-4 PCB layout (2 oz copper, thermal bias), the DMP2039UFDE supports −5.3 A continuous drain current at VGS = −4.5 V. This rating is derived from thermal derating curves in DS35420 Rev. 6-2, Figure 12, and assumes proper copper pour under the exposed drain pad.
Does this MOSFET require an external gate resistor for stability?
No external gate resistor is required for basic switching; the device's Rg = 9.1 Ω and Ciss = 2530 pF yield a natural gate time constant compatible with 1.8 V/3.3 V GPIO drivers. However, a 10 Ω series resistor is recommended when driving from high-speed PWM controllers to damp ringing caused by PCB trace inductance.
Can DMP2039UFDE be used in automotive applications?
The commercial-grade DMP2039UFDE is not AEC-Q101 qualified. For automotive use, Diodes offers the pin-compatible DMP2039UFDQ-7 (Q-suffix), which meets AEC-Q101 stress testing, is PPAP-capable, and manufactured in IATF 16949-certified facilities - listed in their automotive product portal.
How is the exposed drain pad electrically connected?
The bottom-exposed thermal pad is electrically connected to the Drain (pins 5 and 6). It must be soldered to a dedicated PCB copper pour tied to the system power rail - not grounded - to maintain correct potential and ensure thermal performance. Thermal vias beneath the pad are required for RθJA = 63 °C/W operation.
