Product details
Overview
DMP2056UCA4-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in an ultra-small X4-DSN0808-4 package (0.8mm × 0.8mm), rated for -20V VDSS, 64mΩ RDS(ON) @ VGS = -4.5V, and -4.4A continuous drain current at TA = +25°C. It serves as a low-profile load switch in space-constrained portable power rails.
For engineers reviewing the DMP2056UCA4-7 datasheet, DMP2056UCA4-7 pinout, DMP2056UCA4-7 application, or DMP2056UCA4-7 equivalent, key selection criteria include its ultra-compact footprint, gate-threshold stability across temperature (-0.4V to -1.1V), ESD-protected gate-source diode, and thermal resistance of 67°C/W on FR-4 with optimized pad layout.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining fast switching performance: tD(ON) = 6.5ns, tF = 29.5ns, and Qg = 4.9nC @ VGS = -4.5V. Its body diode exhibits VSD = -0.7V @ IS = -1.0A with minimal reverse recovery charge.
The device operates over -55°C to +150°C junction temperature, with normalized RDS(ON) variation ≤1.8× across that range at VGS = -4.5V. Its Ciss = 437pF and Coss = 59pF support high-frequency DC-DC and load-switching topologies requiring tight gate drive control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum blocking voltage before avalanche conduction in load-switch or reverse-polarity protection circuits |
| RDS(ON) | 64mΩ @ VGS = -4.5V - Enables <100mW conduction loss at 4A, critical for battery-powered efficiency |
| ID (cont) | -4.4A @ TA = +25°C - Sustains full-rated current without heatsink on standard FR-4 PCB with 1in² copper |
| VGS(TH) | -0.8V (typ) - Ensures reliable turn-on with low-voltage logic (1.8V/2.5V GPIO) when driven through level-shifting resistors |
| Ciss | 437pF - Limits gate drive current demand and enables clean switching with low-power drivers |
| Qg | 4.9nC @ VGS = -4.5V - Reduces switching energy loss and driver IC stress in high-frequency (>1MHz) applications |
| RθJA | 67°C/W - Achieved with minimum recommended pad layout; allows 1.87W power dissipation at ambient 25°C |
Pinout & Package
Package: X4-DSN0808-4 - ultra-compact 0.8mm × 0.8mm dual-side wettable flank package with NiPdAu-plated terminals, moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal (S) | Connected to system ground or higher potential rail in high-side switch configuration; exposed paddle is electrically tied to source |
| 2 (Gate) | Gate terminal (G) | Control input requiring negative bias relative to source; integrated G-S ESD diode protects against ±6µA leakage at ±8V |
| 3 (Drain) | Drain terminal (D) | Switched output node; handles bidirectional current during body-diode conduction in reverse-current protection |
| 4 (Source) | Source terminal (S) | Second source connection for enhanced thermal and current-carrying capability; must be soldered to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|

| Built-in gate-source ESD protection diode | Withstands HBM ≥2kV without external TVS; eliminates need for discrete ESD components in portable USB/USB-C load switches |
| Low RDS(ON) at low VGS | 80mΩ @ VGS = -2.5V supports direct drive from 3.3V microcontroller outputs without level shifters |
| Thermally enhanced paddle design | Exposed source paddle provides 2.5× lower thermal resistance than non-paddle equivalents, enabling higher current density |
| Halogen- and antimony-free "Green" construction | Meets IEC 61249-2-21:2017; contains <900ppm Br, <900ppm Cl, <1000ppm Sb - compliant for automotive and medical end equipment |

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 |
|---|---|---|---|
| DMN2056UFA4-7 | N-channel counterpart with identical RDS(ON) (64mΩ @ VGS = +4.5V) but requires high-side gate driver or charge pump | Suitable only where board layout permits floating gate drive; not drop-in for existing P-channel schematics | Select if system already uses N-channel biasing infrastructure and thermal constraints allow higher gate drive complexity |
| AO3401A | Larger SOT-23 package (2.9mm × 1.6mm), higher RDS(ON) (85mΩ @ VGS = -4.5V), no built-in G-S ESD diode | Requires external ESD protection and occupies 6× more PCB area; unsuitable for ultra-thin wearables | Choose only when legacy board redesign is impractical and space/ESD requirements are relaxed |
Compared with DMN2056UFA4-7 and AO3401A, DMP2056UCA4-7 delivers superior space efficiency, integrated ESD robustness, and lower conduction loss-making it optimal for next-generation portable and wearable power architectures where footprint and reliability are primary constraints.

FAQ
What is the maximum safe operating temperature for DMP2056UCA4-7?
The junction temperature range is -55°C to +150°C. With RθJA = 67°C/W on FR-4 and 1in² copper, the device sustains 1.87W power dissipation at 25°C ambient. Derating is required above 25°C ambient per Figure 13's transient thermal resistance curve; at 70°C ambient, max continuous power drops to ~1.1W.
Does DMP2056UCA4-7 require external gate resistors for ESD protection?
No. The device integrates a gate-source ESD protection diode rated per JEDEC JS-001 Class 2 (≥2kV HBM), eliminating the need for external series resistors or TVS diodes in typical portable applications. External gate resistors may still be used for EMI suppression or slew-rate control but are not required for ESD robustness.
Can DMP2056UCA4-7 be used in reverse-current protection circuits?
Yes. Its body diode has VSD = -0.7V @ -1.0A and supports bidirectional conduction. When placed between input and output rails with source tied to output, it blocks reverse current flow while allowing forward conduction with minimal voltage drop-ideal for USB-C VBUS protection and battery backup systems.
How does the X4-DSN0808-4 package affect solder reflow profile requirements?
The X4-DSN0808-4 package has moisture sensitivity level 1 per J-STD-020, so baking is not required before reflow. Peak reflow temperature must not exceed 260°C for ≤30 seconds. The dual-side wettable flanks enable automated optical inspection (AOI) of solder joints, and the 0.4mm pitch requires stencil aperture reduction to 75% for optimal paste release.
