Product details
Overview
DMP2042UCP4-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for low-RDS(ON) and fast switching in compact power management circuits. It delivers 37 mΩ @ VGS = −4.5 V, −3.4 A continuous drain current, and operates across −55°C to +150°C - deployed in battery protection and load-switching functions within portable electronics.
For engineers reviewing the DMP2042UCP4-7 datasheet, DMP2042UCP4-7 pinout, DMP2042UCP4-7 application, or DMP2042UCP4-7 equivalent, key selection criteria include gate threshold voltage (−0.8 V typ), thermal resistance (145.7°C/W), package footprint (X1-DSN1010-4), and automotive-grade availability via AEC-Q101 qualification path.
Technical Context
This MOSFET uses a trench-gate silicon process to achieve low on-resistance while maintaining controlled gate charge (Qg = 2.5 nC) and low output capacitance (Coss = 148 pF). Its −20 V VDSS rating supports single-cell Li-ion and USB-powered systems where reverse-polarity protection and efficient power gating are required.
The device features a 0.45 mm profile and SnAg-over-Cu-pillar terminations compatible with fine-pitch reflow. Gate threshold voltage variation is tightly controlled (−0.4 to −1.2 V), enabling stable turn-on behavior across temperature and supply voltage drift in battery-fed applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −20 V: Supports full operation across 0–16 V input rails in portable battery systems. |
| RDS(ON) | 37 mΩ @ VGS = −4.5 V: Enables ≤125 mW conduction loss at 2 A load current. |
| ID (cont) | −3.4 A @ TA = +25°C: Sustains typical peak loads in USB-C PD and smart battery switches. |
| Qg | 2.5 nC: Reduces gate drive power and enables fast turn-on (<0.6 µs delay) with low-side driver ICs. |
| RθJA | 145.7°C/W: Requires minimal PCB copper area for thermal relief in space-constrained layouts. |
| TJ Range | −55°C to +150°C: Validated for extended ambient operation in industrial and automotive-adjacent environments. |
Pinout & Package
Package: X1-DSN1010-4 (Type C), 1.0 mm × 1.0 mm, 0.45 mm height, 4-terminal surface-mount package with exposed drain pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Source terminal | Connected to system ground or higher-potential rail in high-side switch configuration. |
| 2 (Gate) | Control input | Accepts logic-level gate drive; −0.8 V typical VGS(TH) ensures compatibility with 3.3 V microcontrollers. |
| 3 (Drain) | Power output node | Exposed metal pad - must be soldered to PCB thermal pad for RθJA compliance and current handling. |
| 4 (Source) | Source terminal (dual-source) | Second source connection improves current sharing and reduces parasitic inductance in high-frequency switching. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile packaging | 0.45 mm height enables stacking under connectors or beneath displays in ultra-thin devices. |
| Lead-free & halogen-free | SnAg over Cu pillar terminations meet RoHS 3 and JEDEC J-STD-020 Level 1 moisture sensitivity requirements. |
| Low Qgd/Qgs ratio | 0.4 nC / 0.4 nC minimizes Miller-induced shoot-through risk in synchronous buck or OR-ing configurations. |
| Enhanced thermal performance | Exposed drain pad design achieves 145.7°C/W RθJA on standard FR-4 with minimum recommended copper area. |

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 |
|---|---|---|---|
| DMG2305UVT-7 | RDS(ON) = 48 mΩ @ −4.5 V; larger X2-DSN1006-3 package (1.0 × 0.6 mm) | Slightly higher conduction loss; better suited for lower-current, cost-sensitive consumer designs | Select when board space permits slightly larger footprint and thermal margin exceeds 100°C/W. |
| AO3401A | RDS(ON) = 44 mΩ @ −4.5 V; SO-23 package (2.9 × 1.3 mm), 1.1 mm height | Higher profile and larger area; requires more PCB real estate and has higher RθJA (200°C/W) | Choose only if legacy SO-23 footprint compatibility is mandatory and thermal derating is acceptable. |
Compared with DMG2305UVT-7 and AO3401A, DMP2042UCP4-7 offers the lowest RDS(ON) in the smallest footprint and best thermal performance - critical for space-constrained, high-efficiency battery systems requiring minimal voltage drop and fast switching.

FAQ
What is the maximum continuous drain current at 85°C ambient?
At TA = +85°C, the continuous drain current is derated to approximately −2.3 A (based on RθJA = 145.7°C/W and TJ(max) = 150°C). This assumes use of the minimum recommended FR-4 pad layout per Diodes' package outline documentation.
Is DMP2042UCP4-7 qualified for automotive applications?
DMP2042UCP4-7 is not pre-qualified to AEC-Q101, but Diodes Incorporated offers an AEC-Q101-qualified variant (DMP2042UCP4Q-7) with PPAP support and IATF 16949 manufacturing. Customers requiring automotive qualification should specify the "Q" suffix part number.
Can this MOSFET be used in a high-side switch configuration with 3.3 V logic control?
Yes - its −0.8 V typical VGS(TH) and −1.2 V max ensures reliable turn-on with 3.3 V gate drive (VGS = −3.3 V), delivering RDS(ON) ≤ 40 mΩ. No level shifter is needed for standard microcontroller GPIO interfaces.
What is the recommended PCB pad layout for thermal performance?
Diodes specifies a 1.2 mm × 1.2 mm thermal pad with four 0.3 mm diameter vias (to internal ground plane) for optimal RθJA. Full layout guidelines, including solder mask and paste stencil recommendations, are published in Diodes' X1-DSN1010-4 package outline document.
