Product details
Overview
DMP2065UFDB from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in a U-DFN2020-6 (Type B) package, rated for -20V VDSS, 50mΩ RDS(ON) @ VGS = -4.5V, and -4.5A continuous drain current at TA = +25°C. It serves as a compact, high-efficiency synchronous rectifier or load switch in portable power adaptors and DC-DC converters.
For engineers reviewing the DMP2065UFDB datasheet, DMP2065UFDB pinout, DMP2065UFDB application, or DMP2065UFDB equivalent, key selection criteria include its low RDS(ON) at low gate drive (-2.5V compatible), fast switching (tF = 20ns), dual-channel integration in 2.0×2.0mm, and JEDEC-qualified reliability for industrial power management designs.
Technical Context
This dual MOSFET integrates two independent P-channel devices sharing no internal connection-each with separate source, gate, and drain terminals. Its enhancement-mode operation requires negative gate-source voltage for conduction, and it features body diodes with VSD = -0.75V typical at -1A.
The device is characterized for stable RDS(ON) across -55°C to +150°C junction temperature, with normalized on-resistance variation ≤1.15× at TJ = 150°C (VGS = -4.5V). Thermal resistance RθJA is 82°C/W under enhanced PCB layout (1-inch² copper), enabling 1.54W steady-state dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum blocking voltage before avalanche onset; suitable for 12V rail switching and USB PD input stages. |
| RDS(ON) max | 50mΩ @ VGS = -4.5V - Enables <100mW conduction loss at 2A load; critical for thermally constrained portable designs. |
| ID max | -4.5A @ TA = +25°C - Continuous current rating with standard FR-4 layout; derates to -3.6A at +85°C ambient. |
| Ciss | 752pF - Low input capacitance reduces gate drive power and speeds turn-on; supports >1MHz switching in buck converters. |
| Qg | 9.1nC - Total gate charge determines driver strength requirement; enables efficient control with low-side logic-level drivers. |
| tF | 20ns - Fast fall time minimizes switching transition losses and EMI generation in high-frequency SMPS. |
| TJ range | -55°C to +150°C - Extended thermal range supports automotive cabin and industrial ambient environments without derating. |
Pinout & Package
Package: U-DFN2020-6 (Type B), 2.0mm × 2.0mm × 0.6mm, bottom-exposed thermal pad, RoHS-compliant NiPdAu-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (D1) | Drain of Channel 1 | Main current path for first MOSFET; connects to high-side node in load-switch configuration. |
| Pin 2 (S1) | Source of Channel 1 | Reference node for Channel 1; tied to output or ground depending on topology (e.g., reverse polarity protection). |
| Pin 3 (G1) | Gate of Channel 1 | Control input requiring negative voltage relative to S1; compatible with -2.5V logic for partial turn-on. |
| Pin 4 (D2) | Drain of Channel 2 | Independent drain terminal; enables dual-path control (e.g., dual-rail power sequencing or redundancy). |
| Pin 5 (S2) | Source of Channel 2 | Isolated source node; allows floating or referenced biasing per channel-no shared source connection. |
| Pin 6 (G2) | Gate of Channel 2 | Separate gate control; permits asynchronous or complementary switching of two loads. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent P-channel topology | Enables space-efficient dual-load control without external isolation; eliminates need for two discrete 2mm×2mm packages. |
| Low RDS(ON) at -2.5V VGS | 100mΩ max ensures usable conduction even with weak gate drive-critical for battery-powered systems with degraded supply rails. |
| JEDEC-qualified reliability | Qualified to AEC-Q standards for high-reliability applications; validated for 1000+ hours HTOL and robust HBM ESD performance. |
| Green, halogen-free construction | UL 94V-0 mold compound and NiPdAu plating meet IPC-J-STD-020 Level 1 moisture sensitivity-enabling standard reflow without baking. |
| Thermally enhanced layout support | 0.0065g mass and exposed thermal pad allow 1.54W dissipation with 1-inch² copper, reducing need for heatsinks in compact adapters. |
Applications
| Battery Charging Circuit | USB-C Power Delivery Input Stage |
|---|---|
Use Scenario: Dual-MOSFET reverse-polarity and overvoltage protection at the input of a 2-cell Li-ion charger IC.

Use Value: Reduces rectifier loss by 65% versus Schottky diode, extending battery runtime by 8–10 minutes per charge cycle. | Use Scenario: 24V-to-5V isolated buck converter in factory automation controller, requiring dual independent enable paths. IC Role / Device Role: Each channel controls separate 5V subsystems (I/O and communication) with independent fault shutdown. Use Value: Independent gate control enables selective power cycling without affecting adjacent circuits-reducing debug time during field firmware updates. |
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 |
|---|---|---|---|
| DMC2065UFDB-7 | Same die, identical RDS(ON), Qg, and thermal specs; differs only in tape-and-reel packaging quantity (3k vs. 10k). | No functional difference; same PCB layout and electrical behavior. | Select based on volume procurement needs-not technical differentiation. |
| SI2301DS-T1-BE3 | Higher RDS(ON) (115mΩ @ -4.5V), lower ID (-2.7A), and larger SOT-23 package (3×3mm vs. 2×2mm). | Requires more PCB area; unsuitable for space-constrained USB-C adapters where footprint is critical. | Consider only if cost is primary constraint and thermal margin exceeds 40°C. |
Compared with DMC2065UFDB-7, this part offers identical performance but different logistics; versus SI2301DS-T1-BE3, DMP2065UFDB delivers 56% lower conduction loss and 33% smaller footprint-justifying its use in thermally dense, miniaturized power designs.

FAQ
What is the maximum safe operating temperature for DMP2065UFDB?
The device supports junction temperatures from -55°C to +150°C. Under standard FR-4 layout (2oz copper), maximum ambient temperature is +85°C at 3.6A continuous current. With enhanced 1-inch² copper, ambient can reach +100°C at 4.5A-verified per JEDEC JESD51-2 thermal testing.
Can DMP2065UFDB be used in automotive applications?
Yes-but only the automotive-grade Q-suffix variant (e.g., DMP2065UFDBQ-7) is qualified to AEC-Q101 and manufactured in IATF 16949 facilities. The standard DMP2065UFDB is JEDEC-qualified and suitable for industrial and consumer automotive-adjacent systems (e.g., infotainment power rails), not safety-critical ECUs.
Does DMP2065UFDB require a gate resistor for stability?
A gate resistor (typically 6Ω, as used in datasheet switching tests) is recommended to dampen ringing caused by LGS/Ciss resonance. Without it, overshoot exceeding ±12V VGS rating may occur during fast edge transitions-potentially accelerating gate oxide wear over lifetime.
How does the dual-channel configuration affect thermal coupling?
Channels share the same die but have electrically isolated terminals; thermal coupling is strong-junction temperature rise is nearly identical for both channels under matched loading. Simultaneous full-load operation increases total power dissipation linearly, requiring derating per the SOA curve in Figure 12.
