Product details
Overview
DMP22D5UFB4Q-7B from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in X2-DFN1006-3 package, featuring RDS(ON) = 1.9Ω @ VGS = −4.5V, ID = −0.4A, and AEC-Q101 qualification for automotive use. It serves as a compact, low-profile load switch in space-constrained portable and automotive power rails.
For engineers reviewing the DMP22D5UFB4Q-7B datasheet, DMP22D5UFB4Q-7B pinout, DMP22D5UFB4Q-7B application, or DMP22D5UFB4Q-7B equivalent, key selection criteria include gate threshold voltage (−0.4 to −1.0V), ultra-small 0.6 mm² footprint, thermal resistance (RθJA = 272.1°C/W on FR-4), and ESD protection-critical for battery-powered and infotainment subsystems.
Technical Context
This MOSFET operates in enhancement mode with negative gate control, requiring VGS ≤ −0.4V to initiate conduction and fully turning on at VGS = −4.5V. Its low RDS(ON) and fast switching (tD(ON) = 7.3 ns, tF = 97 ns) support high-efficiency DC-DC output stage and reverse-polarity protection circuits.
The integrated gate protection diode and ESD-hardened structure (±10 μA IGSS, HBM > 2 kV per datasheet) enable robust operation in noisy automotive environments. Thermal performance is defined for two mounting conditions: standard FR-4 (RθJA = 272.1°C/W) and thermally enhanced layout (RθJA = 106.2°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −20 V - Maximum drain-source blocking voltage; defines safe operating range in 12V automotive and 5V/3.3V portable systems. |
| RDS(ON) | 1.9 Ω @ VGS = −4.5V - Enables <100 mW conduction loss at −100 mA, critical for low-power always-on circuits. |
| ID (max) | −0.4 A @ TA = +25°C - Supports moderate-current load switching in USB-C port protection and LED bias control. |
| VGS(TH) | −0.4 to −1.0 V - Ensures reliable turn-on from low-voltage microcontrollers (e.g., 1.8V GPIO with level-shifting). |
| Qg | 0.3 nC - Minimizes gate drive energy and switching losses in high-frequency PWM applications up to ~1 MHz. |
| Ciss | 17 pF - Reduces capacitive loading on driving ICs and improves noise immunity in sensitive analog-adjacent layouts. |
| PD | 0.46 W (FR-4) - Limits continuous power handling without thermal vias; requires careful PCB copper area planning. |
Pinout & Package
Package: X2-DFN1006-3 (1.0 × 0.6 mm, 0.4 mm profile), molded green plastic, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (S) | Connected to higher potential in high-side switch configuration; ties to ground in low-side load switch. |
| Pin 2 (Drain) | Drain terminal (D) | Carries switched current to load; exposed pad (Pin 3) is electrically connected to drain for thermal and electrical integrity. |
| Pin 3 (Drain Pad) | Thermal & electrical drain connection | Must be soldered to PCB copper pour for thermal dissipation; not isolated-requires proper isolation in multi-rail designs. |
| Pin 4 (Gate) | Gate terminal (G) | Control input; low threshold enables direct drive from 1.8V/3.3V logic; ESD protection prevents latch-up during hot-plug events. |
Key Features
| Feature | Design Value |
|---|---|
| 0.6 mm² footprint | 13× smaller than SOT-23-enables dense integration in wearables and camera modules where board area is premium. |
| 0.4 mm profile | Supports ultra-thin assemblies (e.g., foldable phone hinge electronics, slim automotive sensors) without mechanical interference. |
| AEC-Q101 qualified | Validated for automotive temperature range (−55°C to +150°C) and PPAP-capable-meets Tier-1 supply chain requirements. |
| ESD protected (HBM) | Withstands ≥2 kV human-body-model discharge-reduces need for external TVS in USB, SD card, and sensor interface paths. |
| Lead-free & halogen-free | Complies with RoHS 3 and "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb)-supports global environmental compliance programs. |
Applications
| USB Port Protection | Automotive Infotainment Power Switch |

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 |
|---|---|---|---|
| DMN2026LFG-7 | RDS(ON) = 2.2 Ω @ −4.5V; larger X1-DFN1212-3 (1.2 × 1.2 mm) package; no AEC-Q101 rating. | Suitable for industrial IoT gateways but not automotive qualified designs. | Select when cost is prioritized over automotive compliance and board area is less constrained. |
| AO3401 | RDS(ON) = 45 mΩ @ −4.5V but in larger SOT-23 package; higher ID = −4.2 A; no AEC-Q101 or ESD hardening. | Better for high-current DC-DC post-regulation, not ultra-compact low-ID applications. | Choose only if higher current capacity and lower RDS(ON) outweigh footprint and qualification needs. |
Compared with DMN2026LFG-7 and AO3401, DMP22D5UFB4Q-7B uniquely balances AEC-Q101 compliance, 0.6 mm² footprint, and −0.4A capability-making it optimal for space-limited automotive and portable designs where qualification and miniaturization are non-negotiable.

FAQ
What is the maximum junction temperature and how does it affect continuous operation?
The DMP22D5UFB4Q-7B has a rated junction temperature range of −55°C to +150°C. At TA = +25°C on a standard FR-4 board, its 0.46 W power dissipation limit corresponds to a ΔT of ~125°C above ambient-meaning sustained operation near 150°C requires thermal vias and copper pours. Derating begins above +70°C ambient per the −0.32 A ID rating.
Can this MOSFET be driven directly from a 1.8V GPIO without level shifting?
Yes-the gate threshold voltage range (−0.4 V to −1.0 V) ensures turn-on with 1.8V logic: applying VGS = −1.8V yields RDS(ON) = 3.4 Ω, sufficient for ≤200 mA loads. However, full enhancement (1.9 Ω) requires −4.5V, so level shifting improves efficiency in higher-current scenarios.
Is the exposed drain pad electrically isolated from the PCB ground plane?
No-the exposed pad (Pin 3) is internally connected to the drain terminal. It must be soldered to a dedicated drain-copper pour, not shared with ground. Improper isolation risks shorting the drain to adjacent ground traces or planes, especially in multi-layer boards with tight spacing.
How does the ESD protection implementation impact system-level transient testing?
The integrated ESD protection diode (rated per HBM ≥2 kV) clamps fast transients on the gate, reducing susceptibility to IEC 61000-4-2 contact discharge. However, it does not replace system-level TVS devices on power or signal lines-gate protection only covers gate-to-source/drain stress, not drain-source surges or data-line ESD.
