Product details
Overview
DMP22D5UFB4Q-7R from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in X2-DFN1006-3 package, optimized for ultra-compact power switching with RDS(ON) = 1.9Ω @ VGS = −4.5V, ID = −0.4A, and AEC-Q101 qualification for automotive use in load-switching and battery protection circuits.
For engineers reviewing the DMP22D5UFB4Q-7R datasheet, DMP22D5UFB4Q-7R pinout, DMP22D5UFB4Q-7R application, or DMP22D5UFB4Q-7R equivalent, this part supports low-voltage portable electronics where footprint (0.6 mm²), profile (0.4 mm), and low gate threshold (−0.4 to −1.0 V) are critical for space-constrained PCB layouts.
Technical Context
This P-channel MOSFET operates as a high-side load switch with gate-driven turn-on at low negative VGS, enabling direct interface with 1.8V/2.5V logic without level shifting. Its ESD-protected structure includes integrated gate protection diode and NiPdAu-plated terminals for robust solderability.
Thermal performance is defined by two RθJA values: 272.1°C/W on minimal FR-4 pad and 106.2°C/W with thermal vias-enabling design flexibility across consumer and automotive ambient conditions (−55°C to +150°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −20 V: Maximum drain-source blocking voltage for 12V automotive and 5V/3.3V system rail protection. |
| RDS(ON) | 1.9 Ω @ VGS = −4.5V: Enables <100 mW conduction loss at −100 mA, suitable for always-on battery switches. |
| ID (max) | −0.4 A @ TA = +25°C: Supports sustained current in compact USB-C port protection and PMIC enable paths. |
| VGS(TH) | −0.4 to −1.0 V: Ensures reliable turn-on with 1.8V GPIOs, eliminating need for external gate drivers. |
| Qg | 0.3 nC: Low gate charge enables fast switching (tF = 97 ns) with minimal drive power in DC-DC sequencing. |
| Ciss | 17 pF: Reduces capacitive loading on control signals in multi-MOSFET power domains. |
| PD | 0.46 W (min pad): Sustains continuous operation in sealed enclosures without forced airflow. |

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 |
|---|---|---|---|
| DMN2016LFG-7 | RDS(ON) = 2.2Ω @ −4.5V, larger X1-DFN1006-3 (1.0 × 0.6 mm same footprint but non-exposed drain) | No AEC-Q101 qualification; rated for commercial temp only (−40°C to +85°C) | Select for cost-sensitive consumer designs where automotive qualification is unnecessary. |
| AO3415 | RDS(ON) = 45mΩ @ −4.5V but in larger SOT-23 package (2.9 × 1.3 mm); higher ID = −4A | Higher current capability but 13× larger footprint and no AEC-Q101 or green compound compliance | Select only when >1A load current is required and board space permits SOT-23 placement. |
Compared with DMN2016LFG-7 and AO3415, DMP22D5UFB4Q-7R uniquely balances AEC-Q101 compliance, 0.4 mm profile, and 0.6 mm² footprint-making it the sole choice for space-constrained automotive and portable electronics requiring production-grade reliability and green materials.

FAQ
Is DMP22D5UFB4Q-7R suitable for hot-swap applications?
Yes. Its −20V VDSS, fast turn-off time (tF = 97 ns), and integrated ESD protection make it appropriate for controlled hot-swap insertion in USB-C and industrial I/O ports. The low RDS(ON) minimizes inrush voltage drop, and the AEC-Q101 qualification ensures robustness against transient stress during plug/unplug cycles.
What is the recommended PCB layout for thermal performance?
For optimal thermal resistance (RθJA = 106.2°C/W), the exposed drain pad must be connected via ≥4 thermal vias (0.3 mm diameter) to an internal or bottom-layer 1-inch² copper pour. Pad dimensions follow Diodes' X2-DFN1006-3 layout: 0.45 × 0.60 mm stencil aperture with 0.20 mm solder mask opening.
Does the gate threshold voltage shift significantly over temperature?
VGS(TH) shifts predictably: from −0.75 V at −55°C to −0.45 V at +150°C (per Figure 8, ID = −250 μA). This negative TC ensures enhanced noise immunity at low temperatures and stable turn-on margin at high temperatures-critical for automotive under-hood operation.
Can DMP22D5UFB4Q-7R replace an N-channel MOSFET in high-side switching?
No-it is a P-channel device designed for high-side switching without external driver circuitry. Replacing an N-channel high-side switch would require redesigning gate drive to deliver negative VGS. Its architecture eliminates bootstrap capacitor needs but mandates logic-level compatibility with negative gate bias relative to source.
