Product details
Overview
DMP1022UWS-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a V-DFN3020-8 package, rated for -12V VDSS, 18mΩ RDS(ON) @ VGS = -4.5V, and -7.2A continuous drain current at TA = +25°C. It integrates ESD-protected gate structure and low input capacitance (2847pF), enabling high-efficiency load switching in compact DC/DC converters and USB power switches.
For engineers reviewing the DMP1022UWS-7 datasheet, DMP1022UWS-7 pinout, DMP1022UWS-7 application, or DMP1022UWS-7 equivalent, key selection criteria include its -12V breakdown rating, sub-20mΩ on-resistance at logic-level gate drive, thermal resistance of 90°C/W under enhanced PCB layout, and compatibility with 1.8V–4.5V control interfaces in space-constrained power rails.
Technical Context
This MOSFET operates as a high-side load switch with gate threshold voltage of -0.35V to -1.0V, ensuring reliable turn-on with standard I/O voltages down to 1.8V. Its low Qg (27nC @ VGS = -4.5V) and fast switching times (tD(ON) = 20ns, tF = 93ns) support high-frequency PWM control in synchronous buck topologies.
The device features an integrated body diode with VSD = -0.8V to -1.2V @ IS = -8A and tRR = 28ns, enabling efficient reverse-current handling in bidirectional power paths. Thermal design is supported by RθJC = 15.6°C/W and validated 150°C maximum junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -12V - Supports rail-to-rail operation in 12V systems with margin against transients. |
| RDS(ON) | 18mΩ @ VGS = -4.5V - Enables ≤120mW conduction loss at 7.2A, critical for thermally constrained layouts. |
| ID (continuous) | -7.2A @ TA = +25°C - Sustains full-rated load without derating on standard FR-4 with 2oz copper thermal pad. |
| Ciss | 2847pF - Low input capacitance reduces gate drive power and improves switching efficiency above 500kHz. |
| Qg | 27nC @ VGS = -4.5V - Allows use with low-current GPIOs or dedicated gate drivers without excessive drive strength. |
| tF | 93ns - Limits switching losses during turn-off in high-duty-cycle applications like always-on power domains. |
| TJ(max) | +150°C - Permits operation in automotive cabin or industrial ambient environments up to +105°C with proper layout. |
Pinout & Package
Package: V-DFN3020-8 (3.0mm × 2.0mm × 0.8mm), bottom-exposed thermal pad, RoHS-compliant NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Four parallel source connections reduce bond-wire inductance and improve current sharing in high-di/dt loads. |
| 5, 6, 7, 8 | Drain (D) | Eight-drain-terminal configuration maximizes thermal conduction to PCB via exposed pad and minimizes RDS(ON) parasitic contribution. |
| Center Pad | Thermal Pad / Drain | Exposed copper pad soldered to PCB ground plane provides primary heat path; electrically tied to drain terminals. |
Key Features
| Feature | Design Value |
|---|---|
| ESD-protected gate | Integrated gate protection diode enables direct connection to unbuffered microcontroller I/O without external clamping. |
| Low RDS(ON) at 2.5V drive | 22mΩ @ VGS = -2.5V supports battery-powered systems using 2.5V or 3.3V logic rails without level-shifting. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets IPC-1752a Class 3 environmental compliance. |
| Fast body diode recovery | tRR = 28ns and QRR = 13nC minimize reverse-recovery losses in synchronous rectification and OR-ing circuits. |
Applications
| USB Type-C Power Delivery Switch | Industrial PLC Digital Output Driver |

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 |
|---|---|---|---|
| DMG1022UVT-7 | Same V-DFN3020-8 package, but RDS(ON) = 22mΩ @ -4.5V and higher Ciss (3200pF); no specified EAS rating. | Limited to lower-current (<6A) or non-inductive loads due to reduced avalanche robustness. | Select when cost sensitivity outweighs need for 9mJ EAS or <18mΩ conduction loss. |
| Si7157DP-T1-GE3 | SO-8 package (larger footprint), RDS(ON) = 15mΩ @ -4.5V, but higher Qg (42nC); rated for -20V VDSS. | Better voltage margin for 16V automotive systems, but requires 2× PCB area and higher gate drive power. | Choose when system-level voltage headroom exceeds 12V and thermal pad access is not constrained. |
Compared with DMG1022UVT-7 and Si7157DP-T1-GE3, DMP1022UWS-7 delivers optimal balance of ultra-compact size, 9mJ avalanche capability, and 27nC gate charge-making it preferred for space-limited, inductive-load applications where both efficiency and ruggedness are required.

FAQ
What is the maximum allowable gate-source voltage for DMP1022UWS-7?
The absolute maximum VGS rating is ±8V, as specified in the Maximum Ratings table. Exceeding this value risks permanent gate oxide damage. For reliable operation, gate drive should be limited to -4.5V for full RDS(ON) performance or -2.5V for logic-level compatibility, with transient spikes clamped below ±7.5V using series resistance or Zener protection.
Does DMP1022UWS-7 require a gate resistor for stability?
A gate resistor (typically 5–22Ω) is recommended to dampen ringing caused by gate loop inductance and prevent unintended oscillation during fast switching. The device's Rg = 9Ω internal gate resistance helps but does not eliminate need for external control; omission may cause shoot-through in half-bridge configurations or EMI in sensitive RF environments.
Can DMP1022UWS-7 be used in linear regulation mode?
No-it is optimized for switching operation only. Its RDS(ON) variation with temperature (Figure 6) and lack of SOA curves beyond pulsed conditions indicate unsuitability for sustained linear-mode bias. Continuous operation in the ohmic region risks thermal runaway due to positive temperature coefficient of RDS(ON) and limited 0.9W steady-state power dissipation.
How is the thermal pad on the V-DFN3020-8 package connected in layout?
The center thermal pad must be soldered directly to a solid copper pour on the PCB, sized ≥3mm × 2mm, with ≥4 thermal vias (0.3mm diameter, filled or capped) connecting to inner ground planes. This achieves the 90°C/W RθJA rating; omitting vias or using isolated pads degrades thermal performance to >135°C/W, risking premature thermal shutdown at >5A loads.
