Product details
Overview
DMP2110UQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -20V VDSS, 80mΩ 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 backlight LED drivers.
For engineers reviewing the DMP2110UQ datasheet, DMP2110UQ pinout, DMP2110UQ application, or DMP2110UQ equivalent, key selection criteria include its AEC-Q101 qualification, low gate charge (6.0nC), fast switching (tF = 9.5ns), and automotive-grade thermal stability up to +150°C junction temperature.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(ON) while maintaining robust body diode performance (VSD = -0.7V @ IS = -1A) and low input capacitance (Ciss = 443pF). Its gate threshold voltage range (-0.45V to -1.0V) ensures reliable turn-on with standard logic-level drive.
The device is characterized for operation across -55°C to +150°C, with normalized RDS(ON) variation ≤1.6× over that range. Thermal resistance is specified at 158°C/W (JEDEC-standard board) and 100°C/W (enhanced pad layout), supporting compact power designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Supports 12V rail switching with 67% voltage margin against transients. |
| RDS(ON) | 80mΩ @ VGS = -4.5V - Enables <100mW conduction loss at 3.5A, critical for thermally constrained SOT23 layouts. |
| Qg | 6.0nC - Reduces gate drive power and enables >1MHz PWM operation in buck converter high-side switches. |
| tF | 9.5ns - Limits switching transition time to minimize overlap losses in synchronous rectification. |
| TJ Range | -55°C to +150°C - Validated for under-hood automotive environments per AEC-Q101 stress testing. |
| Ciss | 443pF - Low input capacitance reduces Miller effect and improves gate drive efficiency. |
| PD (FR-4) | 0.8W - Defines maximum steady-state power dissipation on standard PCB layout without copper pour. |
Pinout & Package

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 | N-channel, 20V, 11mΩ @ VGS = 4.5V - Requires high-side gate driver; lower RDS(ON) but higher system complexity. | Used where bootstrap or charge-pump gate drive is already present; not suitable for simple logic-level control. | Select when efficiency >0.5% improvement justifies added driver IC cost and board area. |
| AO3401 | P-channel, 30V, 85mΩ @ VGS = -4.5V, non-AEC-Q101 - Higher VDSS margin but no automotive qualification or PPAP support. | Targeted at commercial-grade power management; lacks traceability and change control for Tier 1 automotive programs. | Choose for cost-sensitive industrial or consumer designs where AEC-Q101 is not mandated. |
Compared with DMN2011UFD-7 and AO3401, DMP2110UQ uniquely delivers AEC-Q101 compliance, SOT23 footprint compatibility, and verified -20V operation with minimal gate drive overhead-making it optimal for space- and reliability-constrained automotive and industrial power switches.

FAQ
Is DMP2110UQ-13 pin-compatible with other SOT23 P-channel MOSFETs?
Yes, DMP2110UQ-13 uses standard SOT23 pinout (Drain-Gate-Source), matching industry conventions for P-channel devices in this package. Pin compatibility is confirmed by Diodes' mechanical drawing DS42644 Rev. 2 and verified on actual samples. Layout reuse is supported without modification for functionally similar parts like AO3401 or Si2301.
What is the maximum safe operating frequency when used as a synchronous rectifier?
With tF = 9.5ns and tD(OFF) = 24.5ns, DMP2110UQ supports PWM frequencies up to 2.5MHz in buck converters when paired with appropriate gate drive strength. Real-world limit is set by gate charge (6.0nC) and driver capability-not intrinsic switching speed-so 1–2MHz operation is typical for 3.3V/5V logic-driven designs.
Does DMP2110UQ require external gate resistor for EMI suppression?
No external gate resistor is required for basic functionality, but a 10Ω series resistor is recommended to dampen ringing caused by LGS/Ciss resonance during fast transitions. This value balances EMI reduction and switching loss-verified in Diodes' application note AN-2001 for SOT23 MOSFETs in DC-DC topologies.
How does the body diode forward voltage affect efficiency in reverse-current scenarios?
VSD = -0.7V (typical) at -1A defines conduction loss during freewheeling or reverse recovery. In synchronous rectifiers, this voltage drop occurs only briefly before channel conduction begins, contributing <0.7W peak loss. Combined with low QRR (2.0nC), it minimizes energy dissipation during dead-time intervals.
