Product details
Overview
DMP2110UQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -20V VDSS, 80 mΩ RDS(ON) @ VGS = -4.5V, and -3.5A continuous drain current at TA = +25°C. It serves as a high-efficiency load switch or synchronous rectifier in low-voltage DC-DC converters and backlighting circuits.
For engineers reviewing the DMP2110UQ datasheet, DMP2110UQ pinout, DMP2110UQ application, or DMP2110UQ equivalent, key selection criteria include its AEC-Q101 qualification, low gate charge (6.0 nC), fast switching (tF = 9.5 ns), and thermal resistance of 158 °C/W on FR-4 PCB - critical for automotive power management and space-constrained portable designs.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining controlled gate charge and output capacitance (Coss = 59 pF). Its VGS(TH) range of -0.45 V to -1.0 V enables reliable turn-on with logic-level gate drive down to -2.5 V.
The device integrates a body diode with VSD = -0.7 V @ IS = -1 A and tRR = 8.3 ns, supporting efficient synchronous rectification and reverse recovery in buck converters. Its RθJA = 100 °C/W under enhanced copper layout supports 1.2 W power dissipation in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Withstands up to 20 V reverse drain-source voltage without breakdown, suitable for 12 V and 5 V rail switching. |
| RDS(ON) | 80 mΩ @ VGS = -4.5 V - Enables <100 mW conduction loss at 3.5 A, critical for thermally constrained LED drivers. |
| Qg | 6.0 nC - Low total gate charge reduces driver power and enables >1 MHz switching in DC-DC controllers. |
| tF | 9.5 ns - Fast fall time minimizes switching transition losses during high-frequency PWM operation. |
| TJ Range | -55 °C to +150 °C - Supports operation in automotive under-hood and industrial environments. |
| Ciss | 443 pF - Input capacitance impacts gate drive strength requirements and EMI filtering design. |
| ID (max) | -3.5 A @ TA = +25°C - Continuous current rating defines maximum load capability in steady-state power paths. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3 terminals, 0.008 g mass, UL 94V-0 rated molding compound, and matte tin–annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | High-side power path connection | Connected to input supply rail; carries full load current and withstands -20 V reverse bias. |
| Gate (G) | Control terminal | Accepts negative gate drive (-4.5 V typical); threshold voltage (-0.45 to -1.0 V) ensures compatibility with 3.3 V/5 V logic. |
| Source (S) | Reference node / return path | Bonded to PCB ground plane; forms common reference for gate drive and body diode cathode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including infotainment power rails and body control modules. |
| Low RDS(ON) @ VGS = -2.5 V | 110 mΩ enables use with weak gate drivers or partial logic-level control in battery-powered systems. |
| Fast switching with low Qgd | 1.8 nC gate-drain charge minimizes Miller plateau duration, improving hard-switching efficiency. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets automotive environmental standards. |
| Low Coss | 59 pF reduces energy loss during turn-off and improves light-load efficiency in flyback converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2011UFD-7 | Higher RDS(ON) (120 mΩ @ -4.5 V), larger TSOP-6 package, higher Qg (9.5 nC) | Designed for higher-current motor drivers; less suitable for space-constrained backlighting | Choose when board layout allows larger footprint and higher thermal mass is available. |
| AO3401 | Lower VDSS (-30 V), higher RDS(ON) (85 mΩ @ -4.5 V), non-AEC-Q101, higher Ciss (640 pF) | General-purpose industrial use only; lacks automotive qualification and tighter parametric control | Acceptable for cost-sensitive consumer electronics where AEC-Q101 is not required. |
Compared with DMN2011UFD-7 and AO3401, the DMP2110UQ delivers superior thermal performance per unit area (158 °C/W in SOT23), tighter VGS(TH) distribution, and guaranteed AEC-Q101 compliance - making it the preferred choice for automotive lighting and safety-critical power gating where footprint, reliability, and parametric consistency are prioritized.

FAQ
Is the DMP2110UQ suitable for hot-swap applications?
Yes - its -20 V VDSS, low RDS(ON), and 15 A pulsed drain rating support controlled inrush limiting in hot-swap circuits. The device's 100 °C/W thermal resistance under enhanced copper layout enables safe operation during transient overloads, provided gate drive slew rate and external current-limiting resistors are properly sized per application notes AN-7001 and AN-7003.
What is the maximum recommended gate resistor for driving the DMP2110UQ at 2 MHz?
A gate resistor ≤10 Ω is recommended for 2 MHz operation. With Qg = 6.0 nC and typical gate drive strength of 2 A, a 10 Ω resistor yields ~30 ns gate rise/fall time, well within the device's 4.0 ns tD(ON) and 9.5 ns tF specifications. Higher values increase switching losses and may cause shoot-through in half-bridge configurations.
Does the DMP2110UQ require a gate pull-up resistor in high-side switch configuration?
Yes - in high-side P-channel configuration, a pull-up resistor (typically 10–100 kΩ) from gate to source is required to ensure default OFF state during MCU reset or power-up. Without it, floating gate voltage may exceed VGS(TH), causing unintended conduction and potential system damage.
Can the DMP2110UQ replace the Si2301 in an existing design?
Yes, with verification - both are SOT23 P-channel MOSFETs rated for -20 V, but the DMP2110UQ offers lower RDS(ON) (80 mΩ vs. 115 mΩ @ -4.5 V), lower Qg (6.0 nC vs. 7.5 nC), and AEC-Q101 qualification. Layout and thermal validation are required due to differences in SOA curves and junction-to-case thermal impedance.
