Product details
Overview
DMP1022UFDEQ-7 from Diodes Incorporated is a 12V P-channel enhancement-mode MOSFET qualified to AEC-Q101, with RDS(ON) = 16 mΩ @ VGS = −4.5 V, ID = −9.1 A (TA = +25°C), and U-DFN2020-6 (Type E) package. It serves as a high-reliability power switch in automotive engine management systems and DC-DC converters where low-profile, fast switching, and robust ESD protection (3 kV) are required.
For engineers reviewing the DMP1022UFDEQ-7 datasheet, DMP1022UFDEQ-7 pinout, DMP1022UFDEQ-7 application, or DMP1022UFDEQ-7 equivalent, key selection criteria include gate threshold voltage (−0.35 to −0.8 V), thermal resistance (RθJA = 61 °C/W with thermal vias), and AEC-Q101 qualification for automotive-grade deployment.
Technical Context
This MOSFET employs a trench-gate structure optimized for low RDS(ON) and fast switching in high-side load-switching configurations. Its negative VGS(TH) enables direct logic-level drive from 3.3 V or 5 V controllers without level-shifting.
The integrated body diode supports synchronous rectification in buck converters, with tRR = 28–56 ns and QRR = 13–26 nC. Thermal performance is validated under two PCB conditions: standard FR-4 (RθJA = 189 °C/W) and enhanced layout with thermal vias (RθJA = 61 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −12 V - Maximum drain-source blocking voltage for 12 V automotive rail applications |
| RDS(ON) | 16 mΩ @ VGS = −4.5 V - Enables <1 W conduction loss at 8 A continuous current |
| ID (continuous) | −9.1 A @ TA = +25°C - Sustains full-load current in compact DC-DC converter high-side switches |
| Qg | 25.3–38 nC @ VGS = −4.5 V - Supports efficient gate driving with low-power controllers |
| tRR | 28–56 ns - Minimizes switching losses and voltage overshoot during body-diode commutation |
| RθJA | 61 °C/W (with thermal vias) - Allows 2.03 W power dissipation on optimized 2 oz copper PCB |
| VGS(TH) | −0.35 to −0.8 V - Ensures turn-on with standard logic-level outputs, reducing external bias complexity |
Pinout & Package
U-DFN2020-6 (Type E) surface-mount package: 2.0 mm × 2.0 mm footprint, 0.6 mm profile, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Common source connection; electrically tied internally; used for return path and thermal conduction to PCB |
| 4 | Gate (G) | Control terminal; low-threshold input requiring no level shifter for 3.3 V/5 V microcontrollers |
| 5, 6 | Drain (D) | Main power output node; connected to internal die backside; primary heat path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| 0.6 mm profile | Enables use in ultra-thin automotive modules (e.g., body control units) where Z-height is constrained |
| ESD protection | 3 kV HBM rating eliminates need for external transient suppressors in board-level ESD environments |
| AEC-Q101 qualification | Validated for automotive temperature range (−55°C to +150°C) and mechanical stress per PPAP requirements |
| Low RDS(ON) at low VGS | 26 mΩ @ VGS = −1.8 V ensures reliable turn-on even with degraded gate drive due to PCB trace resistance |
| Halogen- and antimony-free | Meets automotive "Green" standards (<900 ppm Br/Cl, <1000 ppm Sb) for end-of-life compliance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1022USD-7 | RDS(ON) = 18 mΩ @ −4.5 V; same U-DFN2020-6 package; lower ID (−7.5 A) | Suitable for lower-current loads (e.g., small solenoids); reduced thermal margin at full 9 A | Select when cost sensitivity outweighs peak current headroom and thermal derating is acceptable |
| SI2301-CDS-T1-GE3 | RDS(ON) = 115 mΩ @ −4.5 V; SOT-23 package; not AEC-Q101 qualified | Limited to non-automotive industrial or consumer use; higher conduction loss increases board temperature rise | Choose only for prototyping or non-automotive designs where qualification and footprint size are secondary |
Compared with DMG1022USD-7, DMP1022UFDEQ-7 delivers 11% lower RDS(ON) and higher current rating, improving thermal headroom in engine bay deployments; versus SI2301-CDS-T1-GE3, it provides AEC-Q101 assurance, 7x lower on-resistance, and 60% smaller footprint-critical for space-constrained automotive modules.

FAQ
What is the maximum junction temperature for continuous operation?
The DMP1022UFDEQ-7 has a rated junction temperature range of −55°C to +150°C. Continuous operation at TJ = +150°C is permitted when thermal design limits steady-state power dissipation to ≤0.42 W on standard FR-4 or ≤1.3 W on thermally enhanced layouts, per datasheet Note 7.
Is a gate resistor required for reliable switching?
A gate resistor (typically 1–10 Ω) is recommended to dampen ringing caused by parasitic inductance in the gate loop. The device's Rg = 8.6–18 Ω (typ/max) and low Qg allow clean switching with minimal external components, but uncontrolled gate drive may cause oscillation or shoot-through in half-bridge configurations.
Can this MOSFET replace an N-channel device in high-side switching?
Yes-it is designed for high-side switching in 12 V systems without requiring a charge pump or bootstrap circuit. Its −0.35 to −0.8 V VGS(TH) ensures full enhancement with logic-level gate drive, unlike most N-channel devices that need ≥10 V gate overdrive for low RDS(ON).
Does the U-DFN2020-6 package require special soldering profiles?
Yes-the U-DFN2020-6 (Type E) package uses a bottom-terminated thermal pad. Reflow must follow J-STD-020 Level 1 moisture sensitivity guidelines and employ a profile with peak temperature ≤260°C, ramp rate ≤3°C/s, and time above 217°C limited to 60–150 seconds to ensure void-free solder joints and mechanical reliability.
